WHAT TO CONSIDER WHEN CHOOSING A 4K GAMING PC?
As well as high quality components, it's vital that you have a monitor which is capable of 4K, or else you aren't going to get the results you're after. With the right monitor, you will also need a powerful graphics card and a great processor to pair it with.
GRAPHICS CARDS
When it comes to choosing a graphics card for your 4K system, the general rule of thumb is that more is more. For consistent 4K gaming at 60FPS, you should be looking for a system with a graphics card that has a minimum of 8GB of video RAM (vRAM).
PROCESSOR
When you're gearing up your 4K gaming rig, don't forget about the real MVP: your CPU. It's the brains behind the operation, so picking a great one is key. Especially if you're eyeing up those silky smooth, high-refresh-rate monitors, you'll want a rig packing serious multi-core power. Why? Because that CPU-GPU tag team is where the magic happens. Your CPU needs to keep up with your graphics card to deliver that pixel-perfect performance.
MEMORY
Whilst your graphics card might steal the spotlight, RAM plays a crucial supporting role in the background. To really elevate your 4K gaming experience, aim for a system packing at least 16GB of DDR4 RAM.
But, if you're a multitasker – gaming while streaming or running a bunch of other programs – consider leveling up to 32GB of DDR4/DDR5 RAM.
What “4K gaming” actually means (and what to expect)
4K (3840×2160) packs four times the pixels of 1080p. The result is vastly increased clarity, finer textures and more immersive vistas. That detail comes at a cost: to keep high frame rates you need significantly more GPU power. At different price/performance points you can expect:
- 60 FPS @ 4K (stable/consistent: Achievable on many modern titles with GPUs like RTX 5070 / 5070 Ti / RX 9070 XT (with settings adjusted).
- High-refresh 4K (120Hz+): Requires top-tier GPUs — RTX 5080 / 5090 or equivalent, and a CPU that avoids bottlenecks.
- 4K with Ray Tracing + DLSS/FSR: DLSS 4 and FSR upscaling can multiply perceived performance while keeping visuals crisp, ideal for enabling ray tracing at playable framerates.

How to choose the right 4K monitor
Your monitor matters as much as your GPU. Consider:
- Panel: IPS or VA for colour/depth; OLED for perfect blacks.
- Refresh rate: 60Hz for cinematic; 120–144Hz for high-refresh gaming.
- Adaptive sync: G-SYNC / FreeSync reduces tearing.
- Ports: DisplayPort 1.4 / HDMI 2.1 for true 4K/120Hz support.

4K Gaming PC FAQs
Do I need a new monitor for 4K gaming?
It depends what you already have! To experience 4K you must have a 4K-capable monitor. Also confirm it supports the refresh rate you want (e.g. 120Hz requires DP 1.4 or HDMI 2.1).
Can I get 4K at 60fps on a £1,500 PC?
You can reach 4K/60 in many titles with careful tuning and a strong GPU (RTX 5070/5070 Ti or AMD equivalent). For high-refresh 4K, plan a higher budget.
Is DLSS / FSR necessary for 4K?
Not necessary, but DLSS 4 and FSR substantially improve playable framerates while preserving visual quality, highly recommended when using ray tracing.
Will my CPU bottleneck 4K?
At 4K, the GPU typically limits performance; however, for high-refresh 4K and streaming, a strong modern CPU (i7/i9 or Ryzen 7/9) is important.
Do you ship prebuilt 4K PCs?
