Hi, I have an early mac pro 2008 with a Mac EVGA 8800 GT installed. I rarely run OSX only Vista Ultimate 64bit via Bootcamp. I am thinking about getting the EVGA 285 GTX upgrade for the system. The price for the Mac version compared to the PC version is 200%! Questions: - Can I just buy a PC EVGA 285 GTX and install it next to my Mac EVGA 8800 GT? - Do I have enough slots and power to run both cards at the same time? - Do I need any kind of special modification of the PC EVGA 285 GTX to run inside Vista Ultimate 64bit via bootcamp? I hope to be able to save money and have both cards installed at the same time: One for boot selection / OSX and one for 3d performance in Vista when needed. Thanks!
