Hey all! I am in the market to buy a mac pro, and I have been reading through the forums and I couldn't find any straight forward information on how to install a 8800GT PC version graphics card on the Mac Pro. On the Apple.com Store it says that for an upgrade 8800GT costs $349.99, damn expensive.. as the NewEgg.com price is $119.99 after rebates. I am really hoping that I can opt out and just get the stock ATI Radeon 2600XT and then buy the PC 8800GT to put in with it. How do you install the PC version 8800GT??? Sorry if this is already been answered, I just couldn't find it. Thanks for your help!
