Choosing a gaming PC can quickly turn into a wall of model numbers.
Graphics cards, processors, RAM, SSDs, cooling systems and power supplies all compete for your attention, and it is easy to assume that bigger numbers automatically mean better gaming.
They don't always.
The right gaming PC depends on the games you want to play, the resolution of your monitor and the level of performance you expect. Someone playing competitive games at 1080p has very different requirements from someone who wants to experience the latest releases at 4K with the graphics settings turned up.
This guide explains the components that really matter and how to choose a gaming PC without paying for performance you are unlikely to use.
Start with the games you want to play
Before choosing a graphics card or processor, start with something much simpler. What do you actually play?
If gaming is only one of the things you'll use your computer for, our Desktop PC Buying Guide takes a broader look at choosing a desktop for home, business, creative and everyday use.
Games vary enormously in how demanding they are.
Titles such as Minecraft, Fortnite, Valorant and other competitive games can run extremely well on relatively modest hardware. Large open-world games, racing simulators and graphically demanding AAA releases can require considerably more performance, particularly at higher resolutions.
It is also worth thinking about the games you are likely to play next year, not just the ones installed today.
You do not necessarily need to future-proof your PC with the most expensive components available, but leaving some performance in reserve can help your system remain capable as new games become more demanding.
1080p, 1440p or 4K gaming?
Your monitor resolution has a huge influence on the gaming PC you need.
The higher the resolution, the more pixels your graphics card has to produce for every frame. That means a PC capable of excellent performance at 1080p may deliver very different results when connected to a 4K monitor.
1080p gaming
Full HD, or 1920 x 1080, remains a popular gaming resolution and is a great choice if you want good performance without spending heavily on the graphics card.
It is particularly well suited to competitive gaming, where high frame rates can be more important than increasing resolution.
A good 1080p gaming PC can also give you more flexibility to increase graphical settings while maintaining smooth performance.
1440p gaming
For many PC gamers, 2560 x 1440 offers an excellent balance.
You get a noticeably sharper image than 1080p without placing the same demands on the graphics card as 4K.
If you are buying a 27-inch gaming monitor, 1440p is particularly attractive and works well for both competitive gaming and visually demanding single-player games.
You will need more GPU performance than you would for 1080p, so the graphics card becomes increasingly important.
4K gaming
Gaming at 3840 x 2160 can produce superb image quality, particularly on larger monitors, but it is considerably more demanding.
If you want high graphical settings and strong frame rates at 4K, expect to spend a larger proportion of your budget on the graphics card.
Technologies such as NVIDIA DLSS and AMD FSR can help improve performance in supported games, but 4K is still a demanding target.
Before paying for a 4K gaming PC, make sure you actually have, or intend to buy, a 4K monitor. There is little point buying hardware specifically for 4K gaming and then using it exclusively with a 1080p display.
The graphics card is one of the most important choices
If you are buying a gaming PC, the graphics card, or GPU, deserves a large part of your attention.
It is responsible for rendering the graphics you see on screen and has a major influence on resolution, graphical settings and frame rate.
Modern gaming PCs commonly use NVIDIA GeForce RTX or AMD Radeon graphics cards.
Rather than simply looking for the highest model number you can afford, think about what you want the GPU to achieve.
For 1080p gaming, a mid-range graphics card may provide everything you need. Moving to 1440p or 4K generally increases the level of GPU performance required.
The types of games you play matter too. Competitive games may prioritise high frame rates, while visually rich single-player games may place greater emphasis on graphical quality, ray tracing and resolution.
What is VRAM and how much do you need?
You will often see graphics cards advertised with figures such as 8GB, 12GB or 16GB of VRAM.
VRAM is memory dedicated to the graphics card. Games use it to store textures, graphical data and other information needed to render what you see on screen.
Higher resolutions and high-resolution texture settings can increase VRAM requirements.
However, you should not choose a graphics card based on VRAM alone. A card with more VRAM is not automatically faster than another GPU with less.
The GPU itself, the games you play, your resolution and the graphical settings you intend to use all need to be considered together.
How important is the processor for gaming?
The graphics card receives a lot of attention in gaming PCs, but the processor still matters.
The CPU handles game logic, physics and many of the calculations happening behind the scenes. It can become particularly important in competitive games, simulation titles, strategy games and situations where you are trying to achieve very high frame rates.
The key is balance.
Putting an extremely powerful processor into a PC with a relatively modest graphics card may not produce much additional gaming performance. Equally, pairing a powerful GPU with an underpowered processor can prevent the graphics card from reaching its potential in some games.
Modern Intel Core, Intel Core Ultra and AMD Ryzen processors all include options capable of excellent gaming performance.
Unless you have a particular reason for choosing one platform, it is often more useful to compare the performance of the complete gaming PC than to focus purely on whether the badge says Intel or AMD.
Intel or AMD for gaming?
There is no simple answer that makes one manufacturer the right choice for every gaming PC.
Both Intel and AMD offer processors suitable for everything from affordable gaming systems to high-end builds.
Performance can vary depending on the individual processor and the game being tested, which is why comparing current processors is more useful than assuming one brand is always faster.
Your other requirements matter too.
If you stream, edit video or use the computer for demanding work as well as gaming, performance outside games may influence your decision.
For most buyers, we would focus on getting the right overall balance between CPU and GPU rather than choosing the PC purely because it contains an Intel or AMD processor.
How much RAM does a gaming PC need?
RAM is another specification where it is easy to assume that more must always be better.
For gaming, there is a point where adding more memory stops making a meaningful difference.
16GB RAM
16GB remains sufficient for many gaming PCs, particularly systems aimed at 1080p gaming and less demanding titles.
It also provides enough memory for everyday computing and general multitasking alongside gaming.
32GB RAM
For a new mid-range or high-performance gaming PC, 32GB is increasingly an attractive choice.
It provides more room for demanding games, background applications, voice chat, web browsers and streaming software without having to worry as much about memory usage.
If you intend to keep your gaming PC for several years, 32GB can also provide some useful headroom.
64GB RAM and above
For gaming alone, most people do not need 64GB RAM.
It starts to make more sense if the same computer is also being used for professional video editing, 3D work, virtual machines or other memory-intensive applications.
Do not pay significantly more for 64GB purely because it sounds better on the specification sheet.
How much SSD storage does a gaming PC need?
Games have become big. Really big.
Once Windows, applications and a handful of modern games are installed, a smaller SSD can fill up remarkably quickly.
For that reason, 1TB is a sensible starting point for many new gaming PCs.
If you tend to keep a large game library installed, 2TB may be much more comfortable.
Look at the type of storage as well as the capacity. Modern gaming PCs generally use NVMe SSDs, which provide fast storage without the mechanical components found in traditional hard drives.
A hard drive can still be useful for inexpensive bulk storage, but we would want Windows and your games running from an SSD.
Also check whether the motherboard has spare M.2 slots if you think you might want to add another SSD later.
Don't overlook cooling
Gaming puts sustained load on your processor and graphics card, which means they generate heat.
Good cooling helps those components operate as intended and can also affect how noisy the PC becomes while gaming.
You will encounter both air-cooled and liquid-cooled gaming PCs.
A well-designed air cooler can be perfectly capable, while liquid cooling is commonly found in higher-performance systems where additional cooling capacity may be useful.
The cooler itself is only part of the story. Case airflow matters too.
A gaming PC needs to bring cool air into the case and remove warm air efficiently. A case covered in RGB lighting may look impressive, but sensible airflow is considerably more useful when you are several hours into a gaming session.
Does the power supply matter?
The power supply is rarely the first specification people look at when buying a gaming PC, but it is an important part of the system.
Your graphics card and processor both require power, and higher-performance components can substantially increase the amount needed.
A suitable power supply should provide enough capacity for the components installed in the PC, with appropriate connections for the graphics card.
Power supply capacity also becomes important if you plan to upgrade your GPU in the future. Installing a significantly more powerful graphics card may require a higher-capacity PSU.
If future upgrades are part of your plan, this is worth checking before you buy.
Can you upgrade a gaming PC later?
One of the attractions of desktop PC gaming is the ability to change components over time.
Depending on the system, you may be able to upgrade the graphics card, add RAM, install additional SSDs or replace other components rather than buying an entirely new computer.
That does not mean every gaming PC is equally upgradeable.
The size of the case, motherboard, available RAM and storage slots, cooling system and power supply can all affect your options.
If you already know that you are likely to upgrade in a couple of years, look beyond today's specification and check what room the system gives you to grow.
Wi-Fi or Ethernet for gaming?
If you can conveniently connect your gaming PC directly to your router or network using Ethernet, it is generally an excellent option.
A wired connection can provide consistent network performance without the interference that can affect wireless connections.
That does not mean Wi-Fi is unsuitable for gaming. Modern Wi-Fi standards can provide excellent performance when used with a good router and strong signal.
If your PC will be located somewhere without easy access to Ethernet, check that Wi-Fi is included rather than assuming it is standard.
Bluetooth is also useful for wireless controllers, headsets and other gaming accessories.
Match your gaming PC to your monitor
Your PC and monitor work as a pair, so it makes sense to choose them together.
There is limited benefit in generating 200 frames per second if you are using a basic 60Hz monitor. Equally, buying a high-resolution 4K gaming monitor can substantially increase the workload placed on your graphics card.
Think about three things together:
Resolution: 1080p, 1440p or 4K.
Refresh rate: How many times the display can update each second.
PC performance: The frame rates your hardware can realistically produce in the games you play.
Getting these three reasonably well matched can make a much bigger difference to the overall gaming experience than simply buying the most expensive PC your budget allows.
For a deeper look at refresh rates, response times, resolutions and gaming displays, read our Gaming Monitor Buying Guide.
What about vray tracing, DLSS and FSR?
Modern games increasingly use technologies that go beyond traditional graphics rendering.
Ray tracing can produce more realistic lighting, reflections and shadows, but it can also place additional demands on the GPU.
Upscaling technologies can help offset some of that performance cost.
NVIDIA DLSS and AMD FSR can render supported games in a way that reduces the workload required to produce the final image, helping improve frame rates.
The exact features available depend on your graphics card and the individual game, so it is worth checking support if a particular technology matters to you.
Do you need an expensive gaming PC?
Not necessarily.
The most expensive gaming PC is only the best choice if you will actually use the performance it provides.
If you play mainly competitive games at 1080p, spending thousands on hardware designed for demanding 4K gaming may achieve very little beyond increasing the price.
On the other hand, buying an entry-level system when your goal is to play demanding new releases at 4K is likely to end in disappointment.
Start with your games, resolution and desired performance. Then choose the hardware that gets you there.
That is a much better way to spend your budget.
