This article is part of our PC-building beginner’s guide. You can view the entire guide here.
Selecting the parts that will make up your PC is, perhaps, the most important part of the process. The hardware you select will determine how fast your PC runs, how quickly it boots, what games (if any) it is capable of running, the speeds at which those games run, how much information can be stored, and much more. You will also need to check for compatibility. The best tool for this, in general, is www.pcpartpicker.com.
PC Part Picker allows you to create a custom build, and they have almost every component in their database that’s available. It will only show you parts that are compatible with the other parts you have added.
If you don’t want to go through the hassle of picking parts, try checking our Parts Lists for compatible components you can use in your builds, as well as the performance they’re benchmarked for in-game. Additionally, see our Buyer’s Guides to find the most cost-efficient and highest performing components.
Regardless of whether or not you opt to use a pre-compiled list of parts, I’d recommend reading this section. It covers the function of each component in further depth and highlights the differences between popular brands and types. Below is a general guide on what to look for in each specific part.
How to choose a motherboard:
You don’t need to spend big on your motherboard. The main factors to consider when choosing one are the number of RAM slots and compatibility with the rest of your components. In specific, CPU compatibility varies greatly between motherboards, since different generations and brands of processors feature different chipsets and socket types.
Chipset is the term used to describe a specific hardware configuration of a motherboard. All motherboards with the same chipset have a certain group of features in common, such as the same CPU socket, PCIe generation supported, RAM generation, and overclockability.
Intel’s most recent motherboards are the 400 and 500-series. These feature an LGA 1200 socket, so they support Intel’s 10th and 11th generation CPUs. Their 300-series motherboards support Intel 8th and 9th generation processors, and have an LGA 1151 socket.
AMD’s most recent motherboards are also 400 and 500-series (Intel and AMD use the same naming conventions for their motherboards to ensure it’s easy to compare between AMD and Intel hardware).
There are specific chipsets within a series. For example, within Intel’s 500-series there are currently four different chipsets: H510, B560, H570, and Z590. These all have different features, such as different numbers of PCIe lanes, different USB and SATA port counts, and different overclockability.
On AMD’s side, their latest generation motherboards have an AM4 socket and include the A520, B550, and X570 chipsets.
There are many different socket types, and each brand has their own exclusive types. Below, we’ll list both AMD and Intel’s most recent sockets, as these are the ones you’re most likely to come across or use in a build.
- LGA 1200 (Intel 10th and 11th generation), 400 and 500 series motherboards
- LGA 1151 (Intel 6th, 7th, 8th, and 9th generations, 100, 200, and 300-series motherboards (Note that 8th and 9th generation CPUs are only compatible with 300-series motherboards (known as LGA 1151 Revision 2), while 6th and 7th generation CPUs will only work with 100 and 200-series chipsets (Revision 1).
You’re unlikely to come across any sockets other than these if buying new, as LGA 1151 is over 5 years old. There is a vast array of other socket types, though, so be sure to do your research if using older parts to ensure chipset and socket compatibility between your motherboard and other components.
- AM4 (Ryzen 1000 to 5000-series), 300, 400, and 500 series motherboards
AM4 has been the standard socket type for AMD since the introduction of their 1000 series (Zen 1) CPUs in early 2017. Additionally, 500-series motherboards are not compatible with 1000 or 2000 series CPUs, despite having the same socket type.
If you opt to use an M.2 storage drive in your PC (which we highly recommend), make sure any motherboard you’re considering buying has an M.2 slot. Otherwise you won’t be able to use your storage drive without buying an expansion card.
All modern chipsets come with some version of PCIe, which is short for Peripheral Component Interconnect Express. PCIe is the interface by which your CPU communicates with most other components. Newer versions of PCIe have higher bandwidth, which translates to better performance.
For example, PCIe 4th generation (the newest revision) has twice the bandwidth of PCIe gen 3. However, it’s important to understand that using PCIe gen 4 won’t always result in higher speeds.
Let’s take PCIe storage drives as an example. PCIe gen 4-capable drives can transfer data at much higher speeds than PCIe gen 3 drives.
Let’s say we have a PCIe gen 4 SSD. For it to transfer data at gen 4 speeds, both the CPU and the motherboard must support 4th-generation PCIe as well. Otherwise the storage drive will only run at gen 3 speeds (PCIe is backwards compatible).
This is an important distinction because it may save you some money. If you’ve already decided on a CPU that only supports PCIe gen 3, such as a 10th-gen Intel processor, there’s no reason to pay extra for a gen 4 storage drive. Its speeds will be limited to those of PCIe gen 3.
Motherboard Form Factors:
Unless you’re building a rig with dual graphics cards (which we wouldn’t recommend) you won’t need more than one PCIe x16 slot (the largest PCIe slot, which the graphics card plugs into). There are three main types of motherboard: ATX, Micro-ATX, and Mini-ITX. While there are many other sizes, they are not nearly as common as these three.
- ATX: This is the full-sized motherboard, and comes with multiple PCIe slots and four RAM slots. It costs more and takes up more space than the other two sizes, but in exchange allows for greater customizability; you can have more RAM and run dual graphics cards if desired.
- Micro-ATX: This is the mid-sized motherboard. It is generally cheaper than its smaller counterpart, and comes complete with two to four RAM slots and one PCIe slot. This should be enough for just about any PC build, since theoretically you could have 128GB of RAM and just about any graphics card.
- Mini-ITX: This is the smallest motherboard, but it’s typically more expensive than a Micro-ATX. It is usually only used when you need to fit your PC in a very tight compartment.
The best course of action is usually to decide what CPU, RAM, graphics card, storage, and case to use first, then choose your Motherboard based on this.
How to choose a CPU:
The CPU is probably the most important component, so it’s important to consider thoroughly when picking one. There are two main brands to choose from: Intel and AMD. There are many generations of CPU’s (Intel is on its 11th generation, and AMD’s Ryzen processors are on their 5th)
Within each brand, there are four main categories to choose from:
This category holds Intel’s Core i3 and AMD’s Ryzen 3 processors. These are the cheapest processors, but also the least powerful. These are typically the best choice if you’re looking to build a PC for basic office-type functions since they’re the most cost-effective Core processor. They’re also great for budget gaming; recent i3 and Ryzen 3 processors like the i3-10100 and Ryzen 3 3100 can easily run AAA games at upwards of 144FPS, making them ideal for budget gaming rigs.
These are Intel’s Core i5 and AMD’s Ryzen 5 processors. These are considered by many to be the ideal gaming processors; they’re not as expensive as an 7 or 9 category, but get similar in-game performance. An i5 or Ryzen 5 is good if you’re looking to build a high-mid tier gaming rig, or if you need to run office-type software (like word processors, Internet browsers, or spreadsheets) at maximum speed.
The 7-tier includes Intel’s Core i7 and AMD’s Ryzen 7 processors. These are extremely powerful processors and are capable of running games at very high framerates when paired with a good graphics card, and capable of running many programs at the same time with no trouble.
7-category CPUs are best if you’re building a PC for more than just gaming, and will be doing things like video editing that will require more cores. They may also be the best option for you if you plan on having a very large number of programs running simultaneously.
These are Intel’s Core i9 and AMD’s Ryzen 9 processors. These are the most powerful CPUs available, and consequently the most expensive. You will only ever need an i9 or Ryzen 9 for the highest-end workstations, so they’re usually only bought by extreme enthusiasts.
Which tier is best for you?
We’ve written two articles covering the differences in both cost and performance of i3, i5, i7, and i9 chips. While we don’t explicitly cover Ryzen CPUs in this write-up, the principles discussed apply to both Ryzen and Intel CPUs.
Another thing you might notice as you search for processors is that some CPUs have a letter tacked on at the end, like the i7-11700K or the Ryzen 3 3200G. These letters at the end of the model denote certain traits. The most common processor suffixes are listed below:
- K: means that a specific processor is unlocked, and able to be overclocked. Intel processors are locked by default, and are not overclockable unless they are a “K” model.
- F: means that a processor requires discrete graphics to operate. Intel processors come with integrated graphics by default, but F-designated processors lack this feature, and need a graphics card to generate an image.
- T: These processors are power-optimized, and generate much less heat than their standard counterparts. They’re also less powerful.
- G: means that the processor has integrated graphics. These are also known as APUs, or Accelerated Processing Units.
- X: means that the processor is has a slightly faster factory clock speed than its non-X counterpart. For example, the Ryzen 5 3600x is slightly faster than the Ryzen 5 3600. In other words, it’s overclocked out of the box.
It’s worth noting that there is a great deal of overlap between these categories in terms of performance. This means that the best i3 is far better than the worst i5, the best i5 is a lot better than the worst i7, and the same goes for the i7 and i9. The Ryzen 5 5600x, for example, outperforms Intel’s i9-9900k in gaming benchmarks.
As a general rule, however, when comparing same-generation processors the i9 is the best, followed by the i7, i5, and i3 in that order. The same applies to Ryzen processors.
Which is better: AMD or Intel?
It’s impossible to say whether one of these two brands are superior. AMD and Intel both manufacture excellent processors, and in the current state of the market neither brand is the definitive best. In terms of gaming performance, Ryzen currently holds four of the top five spots according to the Tom’s Hardware CPU Benchmark Hierarchy (which I’d definitely check out before settling on a processor), but Intel’s high-end processors are still a force to be reckoned with.
While neither brand is definitively better, there are some notable differences between the two. Standard Ryzen processors don’t come with integrated graphics, while Intel ones do. This won’t matter if you intend to buy a graphics card, but if you want a basic PC that doesn’t need high graphics performance, you may want to opt for an Intel CPU and skip the video card.
The other larger difference impacts overclocking. Ryzen CPUs are unlocked, so you can overclock them if you want. Intel CPUs are locked and therefore not overclockable, unless they have a “K” designation, as mentioned above.
On the other hand, Intel generally offers better mid and low-range value. Their Core i7-11700K is better in most metrics than Ryzen’s competing 5800X, and it’s cheaper in most markets. Likewise, Intel’s Core i5-11400 or 11400F is the indisputable king of budget CPUs, and their 11600K offers virtually the same performance as Ryzen’s 5600X at a better cost.
In other words, AMD and Intel both have their role. Intel currently offers better value than AMD in just about every category, but Ryzen holds the title for best performance.
When choosing a CPU then, it’s best to choose based on these general guidelines. Once you have narrowed your choice down to a category, you need to decide which specific processor you want (for example, there are 12 9th-generation i7 processors). When building a gaming rig, decide what kind of performance you want from your PC and what resolution you intend to run it at, and run benchmarks. First, I’d start by looking at this list to get a good idea of how each CPU compares to its peers. Once you have a general idea of what price/quality range you’re interested in buying from, I would test different CPU/Graphics card combinations here to get a reasonable estimate for what framerate you will be able to get, in what games, and on what settings.
If you want to compare two different CPUs with the same graphics card, use this tool. If, say, you’re looking to run Modern Warfare on low settings at 144FPS in 1080p, try different combinations of CPU and GPU to see how cheap you can get your build while still getting the quality you want. Consider the benchmark an overestimate and leave some margin for error, so if you want 144 frames, look for a CPU-GPU combination that gets around 180 in order to play it safe. Games can become less optimized over time (see Fortnite Battle Royale for a great example of this), so it’s best to leave some wiggle room. If you’re building an office-grade PC and don’t intend to buy a graphics card, double-check that the processor you want has integrated graphics before you order it. Without integrated graphics, your processor can’t create an image on the screen, rendering it worthless (I’m sorry).
How to choose a CPU cooler:
Unless you plan to overclock your CPU (boost the speed it runs at to get better performance from it), the default cooler that comes with your processor should be more than adequate. Most high-end processors don’t come with one though, so it’s important to know what to look for when buying one.
The most important factor to consider, by far, is a cooler’s TDP, or Thermal Design Power, rating. TDP actually refers to the amount of heat that a component puts out, but coolers are rated based on how much heat they are able to disperse. A cooler with a TDP of 250W, then, should be able to keep a CPU with a TDP of 250W cool. For reference, the large majority of CPUs are 125W or lower, so a 250W cooler is very powerful.
The best way to decide on a cooler, then, is to look up your CPU’s TDP and buy a cooler that can handle that amount of heat. This is only if you bought a high-end processor, or if you’re looking to overclock yours.
How to choose a graphics card:
The graphics card is another monumentally important part of your PC build. You won’t need a graphics card for basic office utilities, but for things like gaming, 3D rendering, and high-resolution video editing it’s essential to have a graphics card. The graphics card market, much like the CPU market, is dominated by 2 brands. AMD has its Radeon line of graphics cards, while Nvidia has its Geforce line.
Geforce cards can range in performance from can’t-run-Valorant-at-30FPS office-grade GPU’s to the RTX 3090, which is a beast of a graphics card to say the least (It’s the indisputable best consumer-grade card available). Meanwhile, Radeon cards mostly fall into the lower-to-mid tier, but offer a better performance-to-cost ratio.
Choosing your GPU is fairly straightforward. Similar to the CPU-selection process, the best way to decide on your ideal graphics card is to look up benchmarks and figure out what card will meet your needs. Make sure to take your time and whittle your options down before making an ultimate decision.
YouTube is by far the best resource for looking at in-game performance of different graphics cards. Tom’s Hardware has also graced us with an excellent GPU hierarchy list, which you can view here, which should help you find where your prospective graphics card sits in relation to others.
Between these resources, it should be fairly simple to find your ideal graphics card. Find the general range in the hierarchy list that you think will give you the performance you need while not exceeding your budget, pick a specific card, and research performance.
If it performs better than necessary (ie. It gets 300 frames per second in the game you will be playing when you’re only planning to buy an 144hz monitor), you might want to try a less-expensive card in order to get more value while still getting the performance you’re looking for.
Picking a graphics card is a trial-and-error process, so it will probably take a decent amount of research before you finally find the exact one you’re looking for. Keep in mind that your CPU heavily influences your computer’s in-game performance as well, so it may be beneficial to throw a different CPU in the mix as well.
Graphics cards sometimes have suffixes added to the end of them, which denote better performance than the standard version. For Nvidia, these include “Ti” and “Super“, while Radeon cards use “XT.” For example, a 1660 Ti or 1660 Super is better than a regular 1660, and a Radeon 5700XT is better than a 5700. In general, “Ti” cards tend to be marginally better than their “Super” counterparts, but the difference is typically negligible.
A Note on Bottlenecking:
If you buy a CPU that is significantly more powerful than your GPU, or vice versa, this can result in a CPU or GPU bottleneck. What this means is that one piece of hardware is maxing out while the other is not using close to its full potential.
For example, a CPU bottleneck would occur if your processor was running at 100% of its capacity while your graphics card is only at 40%. At the most basic level, this means you inefficiently spent money. Your frames are capped by your CPU’s performance, so even though your graphics card can handle the workload demanded of it easily, its extra power does you no good.
You’d be better off buying a more powerful CPU and spending a little less on your graphics card, since this way you will get more frames per second at the same cost. Ideally both your processor and GPU will be at similar percentages when running games at full blast, as this indicates that your system is efficient.
It’s also worth noting that some games are more CPU-reliant, sometimes referred to as being “CPU bound” or “CPU locked”. Keep in mind that if you plan on playing multiple games, you should be aware of which ones are CPU bound so you can get a more powerful processor if you think that you will be playing these.
How to choose your storage drive(s):
When deciding on a storage drive, the first consideration should, of course, be how much storage you need. If you know you’ll be using your computer to create and store videos, download photos from your phone, install massive games, or house clips you’ll need a decent bit of storage.
I wouldn’t recommend getting less than 1TB of storage most of the time, since storage is immensely cheap (Seagate has a 2TB hard drive for less than 60 bucks).
The one exception to this is if you know you won’t have any storage-heavy media on your computer (i.e. games, videos, or photos). In these instances, you probably don’t need a terabyte and could likely get away with buying 500GB of storage, or even 250 in some instances.
After storage capacity, the real quandary is whether or not to buy an SSD. Solid state drives are a little bit pricier, but they are well worth the money. Your computer will boot much faster, and you can search for and transfer files much more quickly.
Moreover, prices have dropped significantly in the past few years. Cost used to be a major factor when deciding between a solid state or hard drive, but now there are some 1TB SSDs available for under $100. Unless you don’t care at all about boot speeds, spend the extra money on an SSD. The difference is significant, while the cost is not.
Assuming you’re getting an SSD, you must now decide between a NVMe or a SATA model. In the end, it will come down to how much you are willing to spend.
NVMe drives are about 7 times faster than SATA SSDs. For example, the Team GX2 1TB SATA SSD has a max read speed of 530 MB/s, while the PNY CS3030 1TB, an NVMe SSD that costs a tiny bit more, has a max read speed of 3500 MB/s. Read speed is important because, among other reasons, it directly affects how fast your computer boots.
In other words, an NVMe is almost always better in this day and age. If you’re on a tight budget get a low-capacity NVMe for your boot drive (they sell them in sizes as small as 250GB) and use a hard drive to store large files.
To summarize, you need to make sure you get enough storage for your needs. That should be your first priority.
The good news is that all modern motherboards support multiple storage drives, often up to four, so you can always buy another if you’re running low on storage in a year or two.
Secondly, if at all possible, you should purchase an SSD, and preferably an NVMe. It’s worth every penny.
What to look for in an NVMe:
Not all NVMe drives are made equally. Aside from storage capacity, you should look at their maximum read and write speeds. The higher, the better.
Most of the time, read/write speeds are all that matters. If you know you’ll be using your storage drive to write large files frequently, you should look into NAND flash types and how they impact sustained speeds.
We covered this concept in this article, so if you think this will be applicable to you give it a read.
PCIe generation is also important in order to be as cost-efficient as possible. Any modern NVMe drive you look at will be labeled as either “PCIe gen 3″ or PCIe gen 4.”
Gen 4 drives are faster, but they also cost more. If you opt for a gen 4 drive, make sure your motherboard has a 4th-generation M.2 slot. Otherwise, you’ll be paying for faster speeds that you won’t be able to utilize.
How to choose your RAM:
RAM is another component that is typically worth spending a little bit extra on. If you’re on a tight budget you can get by with 8GB of RAM, but you should never drop below that.
It’s also important to note the DDR type of your RAM. DDR4 is the most recent RAM technology that is commonly available on the market, and is about twice as fast as its predecessor DDR3.
Always get DDR4 RAM. In addition to being faster, it has a different form-factor than DDR3, meaning you can’t use DDR3 with modern motherboards. The only exception to this rule is if you’re building with an old DDR3-compatible motherboard. We don’t recommend doing this unless you already have one laying around for some reason.
16GB is generally considered the golden standard for RAM. You can buy a dual-channel 16GB kit for less than $100, and it will serve your needs well.
There’s only about a $20 difference in the cost of typical 8GB and 16GB RAM, and the smoother performance is well worth the slight uptick in cost. For this reason, we’d recommend a 16GB RAM kit unless your budget is extremely limited.
If you expect to have a lot of Chrome tabs, spreadsheets, text documents, videos, or anything of that nature open simultaneously, you may want to invest in a higher amount of RAM (32, 64, or even 128GB in extreme cases). Some editing programs are also RAM-hungry, so research system requirements before building.
If in doubt, know that the majority of people never have occasion to use more than 16GB of RAM. Besides, you can always buy more, DIMM slot count permitting.
All RAM modules come with an advertised clock speed. 3200MHz (3200 cycles per second) is the sweet spot in price to performance. We recommend this for the majority of users.
If you opt for a Ryzen processor you may benefit from faster RAM. 3600MHz is probably your best bet in this scenario. The performance jump won’t be massive, so if you’re on a tight budget don’t sweat it if you need to get 3200.
You’ll also see a number that reflects the CAS latency, generally in the RAM’s product description or product title. It will usually be written as “Cxx” or “CLxx,” like in the example below.
C16 or less is ideal; you’ll find that the majority of 3200MHz RAM is C16. Realistically, you won’t notice the difference in any RAM below 20, but don’t buy memory with a latency higher than that.
How to choose a power supply:
When choosing a power supply, your primary consideration should be its wattage. This is incredibly straightforward. The safest method is to use NewEgg’s Power Supply calculator or a similar tool to see exactly how much power your system will drain. Multiply this number by 1.3 and then round up to the next multiple of 50. That’s the power supply wattage you want.
If that didn’t make sense, here’s an example:
If NewEgg estimates that total system wattage will be 600W, we take:
600 x 1.3, which is 780. Now we round up to the next 50W interval, which is 800. Based on this, We’ll buy an 800W power supply. This is a good rule of thumb to use in order to account for any sudden spikes in energy usage that may occur.
We recommend doing this because most calculators estimate based on a component’s power draw at low usage, rather than at max load. Ten times out of ten, you’ll be better off having too much power rather than too little.
The next most important aspect of a power supply is its modularity. Modularity means, essentially, the customizability of a power supply. Fully modular means that every single power cable can be removed, allowing you to only use cables that are needed. On the other end of the spectrum, non-modular power supplies have all of the cables built-in, and you are unable to remove them.
This means that, with non-modular power supplies, you will probably end up having excess cables that aren’t connected to anything that are still taking up space in your case. The only benefit is that non-modular PSU’s are cheaper.
When choosing a power supply, I would recommend opting for a semi-modular design (a hybrid between non-modular and fully modular), as they are usually the most practical.
The essential cables, such as the ATX cable that powers your motherboard and your CPU cable, are built in. Other cables like the 8-pin used for most graphics cards are modular, so you can use them if needed, but not have extra unused cables in your case.
In the world of computers, if there’s one component you can’t afford to cheap out on it’s the power supply. Your PSU has to be high-quality because a cheaply-built power supply has the potential to ruin the rest of your components, start a fire, and generally wreak havoc on your system.
Because of this, we recommend buying from highly reputable brands. You can’t go wrong with EVGA or Corsair PSUs; these are the two juggernauts of the industry.
BeQuiet! is a newer brand that also produces excellent power supplies. That’s not to say that these three are the only ones you should buy, but do your research before purchasing outside of these brands. Better safe than sorry, right?
Lastly you should give some thought to efficiency, which is usually identified by the “80-Plus” rating. When a PSU sends power to your computer, some percentage of the power from your outlet never reaches the computer, and is instead released as heat.
The more heat is released, the less power reaches the computer and the less efficient the PSU is. This is where the rating system called the “80 Plus system” comes in.
If 18% of the total wattage coming from the wall is lost in transit to your PC, your PSU is 82% efficient, and thus would earn a Bronze rating based on the chart shown above. If only 8% is lost, it would be 92% efficient, and would earn a Titanium rating. This is the premise of the 80 Plus rating system.
Which power supply should you get?
In theory, then, you should always buy a Titanium-rated PSU, right? Not exactly. Take this EVGA fully-modular 650W PSU, for example. At the time of writing, it costs $155, nearly twice as much as the $80 price tag on its bronze counterpart shown here, for only a 9% jump in efficiency at full load.
It would take nearly 10,000 hours, or over a year, of your computer running at full speed to save the $75 extra you spent on the Titanium (assuming a $.12/kwh electricity cost).
Which should you get, then? This entirely depends on your computer’s intended use. If you’re building a PC that you intend to use an absolutely monumental amount, such as for computations or very long-term crypto farming, then it may be worth it to buy a more efficient PSU.
Otherwise, save your money and stick to the Bronze. For 99% of people, the difference in efficiency is negligible, while the price difference is not.
How to choose a case:
The case is one of the more fun parts to choose, since usually it boils down to aesthetics. If you need a case with a CD/DVD tray, SD card reader, or anything else specific make sure to ensure that the one you order has those features.
Look for a case that comes with fans installed, as this will help keep your entire system cool and allow for good airflow. Ideally, you’ll have at least one in both the front and back. Alternatively, you can buy extra system fans if your case is compatible.
If you know you’re going to have to store your tower in a cabinet or tight space, it’s good to check the dimensions and make sure your chosen case will fit. Likewise, if you already have your heart set on a certain motherboard, you will need to double-check that the case is compatible with that motherboard. Cases will have a set list of motherboard types they support so, for example, a smaller case probably won’t support a full-sized ATX motherboard.
It also helps to read reviews and find a case that gets good airflow, especially if you expect your PC to be working hard. Good airflow means you’ll be able to demand more of your computer while still keeping your components in a safe temperature range.
Additionally, different cases have different cable management features. These include compartments that cables can be threaded to, in order to keep them out of sight. These cable management features are invaluable if a messy case bothers you.
Aside from these considerations, picking a case boils down to what you want your PC to look like. Take your time, because you’ll be looking at the case for as long as you have your computer.
How to choose a monitor:
Last but not least comes the monitor. You may already have one if you’re upgrading from an old computer, but if not, you’ll need to select a new one. The five main factors to consider with a monitor are size, response time, refresh rate, resolution, and adjustability.
Size boils down to personal preference and how much space you have. With a higher resolution you should typically get a larger monitor, so 24 inches is ideal for 1080p while 32 is better for 1440p.
Also remember that if you’ll be sitting further away, you’ll probably want a larger monitor than you would otherwise.
Secondly, response time is important (mainly in conjunction with a gaming PC). Response time is the time it takes for a monitor to switch from one color to another. It sounds abstract, but in essence a lower response time means your monitor will be more responsive when playing games and display the image in closer-to-real-time.
It’s difficult to notice any difference between a 10ms and 1ms response time, but you should aim to buy one that’s 10ms or lower. Most good monitors these days are in the 1ms to 5ms range anyway, so it doesn’t make sense to settle for less.
At this point you should have already decided on the rest of your components, and should have a good idea of what frame rate you’ll be running games at. Your monitor should make full use of the frames your computer gets, so if your PC gets 144FPS on most games, you should buy an 144hz monitor. If it gets 240FPS, get a 240hz monitor.
When on a budget, 144hz is usually the golden standard, since the jump from 60 to 144FPS is massive compared to the jump from 144 to 240. If you can’t afford that, 60hz is still fine, especially if you’re not playing games competitively, but shoot for 144hz if at all possible.
They’re very affordable; there are even some for less than $150with a 1ms response time. If you won’t be playing games on your PC, refresh rate still affects your overall experience. 144hz makes everything feel smoother, not just games, so a higher refresh-rate monitor may be worth the extra money.
Next is resolution, which goes hand-in-hand with refresh rate. Your monitor’s resolution will directly impact the framerate you’re able to get, and the refresh rate you need. By this point, you should already have a specific resolution in mind, so buy a monitor that supports your desired resolution.
Higher resolutions will display higher levels of detail, but will also be harder on your GPU in-game, resulting in lower frames.
As a last consideration, look into your monitor’s adjustability. Some come with an adjustable arm that allows you to move the screen up and down, which will allow you to view the screen at the desired height, rather than having to strain your neck. If this is important to you, make sure you get a monitor that includes this feature.
As a final precaution, before you order anything put all of your parts into PC Part Picker if you haven’t already done so. It doesn’t take much time, and it should catch any compatibility errors that may arise. Doing this will help you avoid the unpleasant scenario in which your parts arrive, only for you to find that they’re somehow incompatible.
