Pros

Verdict
Our verdict on the Core i7-7740X
A four-core, eight-thread Kaby Lake-X desktop chip that’s fast in lightly threaded apps but bafflingly limited for its platform.
Get it if you need a fast quad-core for older games or apps that hate multi-threading. Skip it if you want modern multi-core performance or plan to upgrade later.
Buy it if…
- You want a basic workstation with a fast single-core for old games.
- You need a cheap way to test a high-end motherboard.
- You are building a retro overclocking rig for fun.
