I have the 2008 mac pro with the 8800 on it and partitioned the 500GB HD with 150GB for Windows XP. I am a heavy gamer and when Vista becomes essential I want to get it along with the 9800 GX2 or upcoming GTX. I want to install it on my Mac Pro. I here that it requires an Eight PIN Power Connector and I dont think the Mac Pro has one? Does it? what have others done? Please i need feedback!
