I bought an untested 8800 Ultra off eBay to use in my machine was a PhysX card (for teh lulz), but I can't use it. With my 580 in the primary slot and the Ultra in the secondary slot, the 580 loses picture when I boot into Windows. On its own, the Ultra has graphical corruption at the BIOS. Basically, does my Ultra need baking? If so, how would I go about doing it?
