Yes, I am. I actually didn't have to install another driver or anything. I just disabled SLI, and it was done. I checked in the Device Manager and it appears that they are both using the same version driver (both dated 7/14/09), so I just left it alone.
On a side note. For anyone thinking about this setup. It creates a LOT of heat. My liquid cooling system which is rated up to 1000watts is running full tilt, and temps are hovering around 70C all the way around, when they are normally 60C and below. This is high for liquid cooling, but I don't think I could do it with air cooling. My temps would be through the roof.
It sure does rock though!
