Has anyone upgraded their Mac Pro to run the new nVidia GeForce 8800 GT graphics card and use BootCamp Win XP x64? I found a driver on the nVidia website that seem to suggest that the card can be run using XP x64. http://www.nvidia.com/object/winxp64_169.21_whql.html it isn't linked straight from the card page however. Just wanted to check here before I go and spend $280 on the card. I am running the ATI card right now. ------------- Never mind... after reading more barefeats.com reviews I realized that my ATI 1900 is actually superior for my needs. Sorry for taking up the bandwidth.
