Hi Guys, I've got a Early 2008 Mac Pro and am wondering what Graphics Card should I opt for? I plan on getting a PC Graphics Card since the Mac based ones are insanely expensive. I'm aware of the no boot screen but I don't mind that issue. My Options - Radeon 7870 - Radeon 7950 - GTX 650Ti - R9 280X - Radeon 6870 - GTX 660 If anyone could give me confirmation on what PC GPU's worked for them that would be great. I already tried my brothers XFX R280 and ASUS 6950 without any luck, only booted in safe mode.
