4K gaming at max settings is GPU-intensive. Rendering four times the pixels of 1080p means your graphics card needs to work significantly harder — and the difference between a machine that “runs 4K” and one that genuinely delivers it is enormous.

What it takes
A machine that delivers smooth 4K gaming needs a GPU capable of pushing 60+ FPS at 3840×2160 in demanding titles — which in 2026 means RTX 4080 Super or better. Just as important is matching your GPU with a CPU that won't bottleneck it. We pair RTX 4090 builds with Intel Core i9 or AMD Ryzen 9 processors and fast DDR5 memory to ensure your GPU is never starved of data.
Indicative 4K FPS · RTX 4090 + Core i9 build
IndicativeOur 4K flagship
Built specifically for 4K. Intel Core i9-14900K, RTX 4090, 64GB DDR5, 4TB NVMe Gen4 storage, and an 850W 80+ Gold PSU — the best gaming experience available from a consumer PC in 2026.
The accessible flagship
Not everyone needs the absolute maximum. The RTX 4080 Super delivers excellent 4K performance in most titles at a meaningfully lower price than the 4090. Our mid-range 4K builds offer a great balance of ultra HD performance and value. Configure yours here.
Common questions
For comfortable 4K gaming at high settings and good framerates, the NVIDIA RTX 4080 Super or RTX 4090 are the recommended choices in 2026. The RTX 4090 remains the only card to deliver consistent 60+ FPS in demanding titles at full 4K ultra settings.
A capable 4K gaming PC with an RTX 4080 starts from around £1,800. An RTX 4090 build typically starts from around £2,200. Forge PC builds all 4K rigs with components matched to eliminate CPU bottlenecks.
If you have a 4K monitor, yes. The visual improvement over 1440p is significant, especially on large screens (32"+ monitors). 4K removes the aliasing artefacts visible at lower resolutions and delivers a cinema-quality image.
4K monitors now come in 60Hz, 120Hz, and 144Hz variants. For smooth gameplay, a 120Hz+ 4K display is recommended. The RTX 4090 can push 100+ FPS at 4K in many modern titles.
We specialise in PC builds rather than full system bundles. We can recommend monitor pairings, but monitors are purchased separately.
