Since the 8800GT for mac pro 2009 has been confirmed that it won't work in older mac pros, I've decided the turn my mac pro into pc. I know this kind of topic has been asked several times, but I really want to have a definite answer if ANY PC cards can run on bootcamp windows 100%. I've heard about the power supply issue, the PCI-e slot, EFI and BIOS... I'm not a hardware guy, I don't really know what's all these about, I just want to make sure when i got a pc card, I follow all the proper installation procedures, and it will work. An apple guy told me if i wish to run a PC card, it's a 50/50 chance, there is no definite answer, which means i might fail and wasted my money. Even if I'm lucky, I may have to replace certain cables or some sort of stuff in order to run it properly. Any mac pro user with pc cards can comment on that? thanks in advance.
