Re: GPU overclocking
Welcome to Tech-Forums, woltej!!!
Rivatuner is a great all around overclocking tool. And works with both Nvidia and ATi cards.
Though for Nvidia cards I found it much easier to overclock with EVGA Precision, like Slay suggested.
And +1 on Furmark to stress for stability. Heats up graphic cards more than anything. Be careful with that one.
