Actually I sold my 580, only owning 680 atm and they are my main build. This build is a gift from me to my friend since her laptop died last month. That's why I said "no overclock" just because the user won't be me
If I go for 7950, this will be the first time I've ever use Radeon in my life. I hope it's going to be fine.
Btw, do you know anything about ASUS HD7950-DC2T the first version. Why would they remove it from the store?
