PC gaming looks complicated because the talk around it is full of model numbers and benchmark charts. Strip that away and the decisions are fairly simple: what the computer needs to do, whether to buy one ready-made or build it, what to plug it into, and where to buy games. Here is each one in turn.
The parts that matter, and what they do
The graphics card does most of the heavy lifting in games and deserves the largest share of your budget. The processor (CPU) handles game logic, physics and everything happening in the background; a sensible mid-range chip is plenty for most players. Memory (RAM) holds what the game is using right now, and 16GB is a reasonable minimum for current releases, with 32GB giving more breathing room. Storage should be a solid-state drive, ideally an NVMe model, because large modern games load far faster from one.
A good power supply from a reputable brand protects everything else, the motherboard needs to match your processor, and a case with decent airflow keeps the system quiet. Check a game’s listed system requirements before buying hardware; publishers give minimum and recommended specs, and aiming for the recommended level is a sensible target.
Prebuilt or build your own?
Building a PC is more approachable than it looks, and it teaches you how the machine works, which makes future upgrades easy. The trade-off is time and risk: if something does not work, you are the one diagnosing it, and each part has its own separate warranty.
A prebuilt from a reputable UK system builder comes tested, with one warranty covering the whole machine and someone to call when it fails. Prices have also become harder to compare on parts: memory and storage costs climbed sharply at the end of 2025, and IDC reported that major PC makers were announcing price rises in response, driven by memory makers prioritising AI data centres. At the time of writing, it is worth pricing both routes rather than assuming building is always cheaper. If you are buying second-hand, make sure the machine can run Windows 11, as Windows 10 reached end of support on 14 October 2025.
Monitor, peripherals and where to buy games
The monitor shapes the experience as much as the PC. A 1080p screen is the easiest resolution to drive, 1440p is a popular step up for mid-range graphics cards, and 4K needs serious hardware. Refresh rate matters too: a 144Hz or faster display makes motion noticeably smoother, provided your PC can produce the frame rates to match.
For games, Steam is the biggest PC store and where most people start. The Epic Games Store regularly gives away free games, GOG sells titles without copy protection, and PC Game Pass offers a subscription library through the Xbox app. Publishers such as EA and Ubisoft also run their own launchers, which some games require even if bought elsewhere.
Common beginner mistakes
- Spending heavily on the processor and skimping on the graphics card.
- Buying a high refresh rate monitor the PC cannot keep up with.
- Choosing an unbranded power supply to save a small amount.
- Forgetting to plug the monitor cable into the graphics card rather than the motherboard.
- Not installing the latest graphics drivers after setup.
Quick questions
Can I play PC games on a laptop?
Yes, gaming laptops exist and suit people who need portability. Expect less performance for the money than a desktop, more fan noise and far fewer upgrade options, as most parts are fixed in place. Check the graphics chip model and the wattage it is allowed to draw, since the same chip can perform very differently between laptops.
Do I need Windows to game on a PC?
Most people use Windows because nearly every game supports it. Linux has become a workable option thanks to Valve’s Proton compatibility layer, which runs many Windows games through Steam, but some online games with anti-cheat software still refuse to launch. For a first gaming PC, Windows remains the least troublesome choice.
Can I use a controller on PC?
Yes. Xbox and PlayStation controllers both work on PC, and Steam includes settings that let you remap buttons and use other pads too. Racing and action games often feel better on a pad, while strategy games and shooters suit a keyboard and mouse.
