The Best Gaming PCs for 4K
Six 4K gaming PCs with an X3D processor, from RTX 5090 to RTX 5080, each with its CPU, graphics, memory and storage named.
By Alex Morgan, PC Hardware Editor
12 min read6 products evaluated
For 4K, these six pair an RTX 5080 or RTX 5090 with an AMD X3D processor, so neither part holds the other back.
We compared the parts each listing names: CPU, graphics card and VRAM, memory, storage and, where stated, the power supply and warranty. We did not test these systems, and we skipped listings that leave a core part vague.

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 set side by side six prebuilt PCs on graphics card, VRAM, processor and memory, using each maker's published specs. We did not test them in-house, and power supply wattage and PSU rating are missing for at least one pick.
- What every pick has in common
- All 6, from the MAINGEAR MG-1 to the Ultra 50 V3, state graphics card, VRAM and processor.
- Where the specs have gaps
- The Infinite ZS, the Panorama XL, the Panorama XL 9950X3D 5090 and the Panorama XL 128GB give no power supply wattage; the Infinite ZS, the Panorama XL, the Panorama XL 9950X3D 5090 and the Panorama XL 128GB give no PSU rating.
- Price range
- From the Ultra 50 V3 to the Panorama XL 128GB, all sat in the over $1500 tier when we checked.
