Gaming PC Buyers Guide
How to choose a gaming PC

Unlike consoles which are available in just a handful of different models, PCs are available in a huge variety of configurations. This is both a strength, in that you have a lot of choice over how much you can spend but has a weakness because so many choices can seem overwhelming. This guide quickly and concisely highlights the main things you need to consider when buying a gaming PC, broken down into three easy steps.

PC Performance
The most important component in a gaming PC is the graphics card or GPU. This is because the graphics card determines what resolution and quality settings your PC will be able to play games at, with higher performance enabling you ramp up both settings for a better gaming experience. The graphics card is also the most expensive component in a gaming PC, so has the biggest impact on the total system price.
For this reason we categorise our gaming PCs by which graphics card they have and for each category give a broad indication of the cards abilities using the simple ratings of High-End, Mid-Range and Entry-Level.
The frontrunner in graphics cards is NVIDIA, and so you’ll see most 3XS gaming PCs featuring one of these GeForce cards.
NVIDIA GeForce RTX Graphics Cards

The most powerful and advanced NVIDIA gaming graphics cards belong to the GeForce RTX 30-series, although you’ll still see some PCs with less powerful previous generation RTX 20-series and GTX 16-series graphics cards listed on our website. The GeForce RTX range comprises close to a dozen models spanning all the way from Entry-Level GPUs costing hundreds of pounds all the way up to High-End GPUs that cost over a thousand pounds.

GeForce RTX 30-series GPUs support the latest Microsoft DirectX 12 Ultimate standard, which enables stunning DXR ray tracing, plus many proprietary NVIDIA technologies to improve your gaming experience such as DLSS, Reflex, Broadcast, RTX IO and Omniverse Machinima.
