I have been looking through these forums for details on overclocking a 7900GTX however I cannot seem to find anything. I think the search on this forum is broke!
Can anyone give me some guidelines on how far this card can be oc'ed?
You can also use Rivatuner to oc the card and Atitool to stress the card and scan for artifacts. Rivatuner lets you do many things like fan speed, save or load overclocking profile, etc.
