12 min read5 products evaluated
4K gaming leans on the graphics card more than any other part. These five use an RTX 5080 or RTX 5090, the cards with the most graphics memory in the prebuilts we researched.
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.

Why we like it
It also comes with a 240mm liquid cooler on a Core Ultra 9 285K. Its PSU wattage isn't published, so ask the seller before a GPU upgrade. It is the only pick here with a core Ultra 9 285K processor; the Ultra 50 V3 has a ryzen 7 9800X3D processor instead.
Like the STORMCRAFT Phantom, it has a DDR5 memory type, while the ZOTAC MEK uses a DDR5-6000 memory type. It also comes with a bundled three-year antivirus licence.
