Ok mate I appreciate your advice. I think I may have to reapply my thermal paste as stupidly I used the stuff that was pre applied on the heat sink rather than getting some Arctic silver 5. then re overclock to 3GHz. And your first suggestion i can not do as again stupidly i didnt get a motherboard that supported 2 PCIE slots lol
Nevermind, i was just curious as to why i was getting the same performance from my GTX460 as i was when i had my 9800GT ! which i only paid 80 for.
