If you experience issues while using the ASUS drivers, try switching over to the generic Forceware drivers. Out of both, the Forceware drivers seem to be the most solid. My recommendation still stands with version 56.72, I've had the best luck with it thus far.
Is it possible to flash the bios on my vcard so I'm not so limited in my oc's? Oc'ing is something I'm still new to, and BIOS flashing is something I've tried to avoid but am now seeing I'll need to learn.
If possible, where can I get a non-ASUS VGA bios from? Sorry if this is a rather non-intellectual question.
