Decent, good, better, best type grid listing for gaming computer upgrades or builds.

It's by no means definitive. But it's a great place to start and they include pricing, and it's frequently updated.

I've found them to be pretty conservative compare to some enthusiast sites.

I've used them for my last several builds, at least as a place to start.

I would also suggest https://www.reddit.com/r/buildapc/ if you're looking for specific questions answered or general knowledge, they are a very decent community.
