Build a PC / heavy gaming

$4,500 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: $5,036 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. A price marked Amazon US is ScoutPrices' reading of the listing its button opens, dated; the rest are typical prices. Not a checkout total: no operating system, shipping, tax, screen, keyboard or mouse.

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

The ASUS ROG Strix X870E-E Gaming WiFi goes onto the Lian Li O11 Dynamic Evo RGB's tray: ATX, X870E, nine standoffs.

The AMD Ryzen 7 9850X3D drops into the AM5 socket, lever down: 8 cores, up to 5.6 GHz.

The Arctic Liquid Freezer III Pro 360's block sits on the chip and its 360 mm radiator bolts to the roof; rated 330 W against 162 W.

Two sticks of G.Skill Trident Z5 RGB 32GB (2x16GB) DDR5-6400 CL32 click into the second and fourth slots: 32 GB at 6400 MT/s.

The Samsung 9100 Pro 2TB screws into the first M.2 slot, the WD Black SN8100 4TB into the second.

The GeForce RTX 5080 slides into the x16 slot and latches: 310 mm in a case that takes 422 mm, 16 GB of memory.

The Super Flower Leadex VII XG 1000W goes into the basement, 1000 W for a build that draws about 750 W flat out, one native 16-pin cable to the card.

Side panel on, 7 case fans spinning. Fit for the job: 84 of 100.
