Build a PC / office & everyday

$4,500 office PC, part by part

An Intel Core Ultra 7 270K Plus with the GeForce RTX 5080, and the 6 parts around them that fit it: $3,967 all in.

A desk that never stutters: browser, documents, calls and 1080p video, on two or three screens. Every part here was checked against every other for fit, and picked for snappy single-core speed, quiet running, and a card that drives two or three screens without fuss. 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 $3,967 rather than spend the rest of the budget on a bigger number. $533 is left for a screen, a keyboard and a mouse.

The Intel Core Ultra 7 270K Plus and the GeForce RTX 5080 are well matched at 1080p.
