the forums on tomshardware are better than the site itself. There are some great articles about components and best for your money etc - I use those when I want do to some upgrading. Other than that, there isn't much of anything out there great because almost every site is paid by some advertiser to push their stuff and nothing is independently reviewed.
I used to like 1up.com but that's trash. Gametrailers used to be good but that's all dumb. IGN is all advertisements now. Just use google or bing when you want to know about something in particular.
