Actually I didn't have and still don't have the intention to overclock. I always think you're way better off, in price AND in effort, buying a better card.
Take the "MSI R6970 Lightning" for instance. Now THAT's a card! At only about 80 Euros more I think that's what I'm gonna go for. Yep that it is!
I firstly wanna thank you guys! And secondly...bye!
