The new Beta drivers from nVIDIA, I think you can only get them from the gaming section of www.nvidia.com but they boosted my 3D-Mark 05 score tons since I used them.
Awesome stuff, BTW I tend to stay away from the custom drivers in fear that my hardware will get damaged.
Well a lot of people are criticizing ledtek is making a "lite" version of the 6800GT. I am not sure about that, but certainly nobody have complained about eVGA.
And to U-Toast go to www.nzone.com to get the beta drives.
