Build a PC / heavy gaming

$5,500 4K gaming PC, part by part

An AMD Ryzen 7 9850X3D with the GeForce RTX 5080, and the 6 parts around them that fit it: $4,010 all in.

One of the three heavy targets at a time, and the result says which: 4K high settings by default, with ray tracing or 240 Hz at 1440p as the alternatives the same class of card serves. Every part here was checked against every other for fit, and picked for the strongest graphics card the budget allows. Typical US prices read on 2026-09-09, not a live checkout total: no operating system, shipping, tax, screen, keyboard or mouse.

Everything past this costs far more than the speed it adds, so the build stops at $4,010 rather than spend the rest of the budget on a bigger number. $1,490 is left for a screen, a keyboard and a mouse.

The AMD Ryzen 7 9850X3D and the GeForce RTX 5080 are well matched at 4K.
