I found this site. Very informative.http://cpuboss.com/ Thinking of buying a new CPU? This is a good place to check first.
Yeh very nice site. Your thinking of buying a new cpu?You already have the best Ivy bridge cpu. EDIT: Sorry i misunderstood your post i thought you wanted to buy a new cpu, and it is a good informative site for users upgrading or buying a new pc to decide what cpu to get.
All info about CPU's you need . Good site tho. https://www.youtube.com/watch?v=cNN_tTXABUA Also this one: http://www.hardware-infos.com/prozessoren.php It's on German, but have much more info (especially on GPU's) than most of the sites online. You will get your way around i guess . PS: Don't look at rankings, since those are partly accurate, and creators of rankings don't claim it.
