12 min read5 products evaluated
4K gaming needs an RTX 5070 Ti or better. Every pick uses an RTX 5070 Ti, 5080, 5090 or RX 9070 XT, ordered by VRAM.
This is a research roundup, not a lab test: graphics card, VRAM and processor come from each maker's published specs; a missing memory type is flagged, not filled in, and no figure here comes from our own testing.

How We Chose These Gaming PCs for 4K
Alex Morgan compared the manufacturer specifications, connectivity, warranty terms and compatibility of every pick. Figures come from the makers unless a third-party source is named; we did not test these products ourselves.
- The figures behind the order
- We lined up five prebuilt PCs on graphics card, VRAM, processor and memory, using each maker's published specs. These are research figures, not bench results: 1 of 5 picks leave out memory type.
- The shared baseline
- All 5, from the Skytech 9950X3D RTX 5090 to the MEK 5070 Ti, state graphics card, VRAM and processor.
- Where the specs have gaps
