I just got this card on Saturday and noticed that using the drivers that came with it, especially the Expert Tool overclocking utility created a mass of problems. Firstly, visual artifacts in 3D Mark 2001 and secondly complete inability to overclock the board so bad as the card would cause the system to lock up requiring hard reboot at even 420/480 - an enhanced setting at which the card is guaranteed to work.
So far with bad news... The nice bit is that switching to Nvidia ref. drivers 12.41/12.90 resulted in complete rectification of the above problems as well as an 100% stable overclock to 245/540. The card does not seem to have a slightest problem running at these speeds and could be further pushed but this is sth. I am reluctant to do at this stage.
The remaining problem is that I can't use the VIVO functions as these are only supported with the Gainward's driver set, I believe. Anyone experiencing similar problems here?
