Help (please!) -- just installed the 8800G in my 2008 Mac Pro. No problems under 10.5.2, but under Boot Camp (Vista Ultimate), I cannot get the system to recognize the card, and it keeps installing it as the SVGA adapter. I've tried installing the driver from Nvidia, but the installer tells me that there's no driver for the hardware installed, and I've tried reinstalling the boot camp drivers, but nothing has worked! Any suggestions? Thanks in advance.
