8800GT doesn't support Aero on Vista Business 64-bit
I just installed Windows Vista Business 64-bit. It seems like all my drivers were installed automatically because I can hear sound and go on the Internet. The only thing broken is that it defaulted to Vista Basic theme. I could not locate the Aero theme in the dropdown menu. Do I need some special driver for my GeForce 8800GT 512 MB to work? I went to nVidia.com and saw that the 8800GT does not have drivers for Vista 64-bit...
