Hi Guys, I've done quite a bit of reading, but most times I come away a little confused. I apologise in advance if this has been answered before. I'm looking at getting a Macpro 5,1 quad 2.8 it will come standard with the 5770 video card. Question can I drop in a faster PC video card e.g. GTX 570 or AMD equivalent (without flashing it and without patching the OS) and run both card 5770 and PC video card concurrently? I do not plan to bootcamp so, can I game (diablo 3) using the pc video card as opposed to using the 5770? I understand Lion has driver support now for some nvidia and AMD cards so am I correct in "hoping" that a un-flashed pc video card can work in OSX Lion without any patching. Going back to my example of playing diablo 3, can OSX make use of the pc video card for diablo? I hope the above make sense?? Just to cover some other things off. I don't not plan on getting a PC for gaming I do not plan on boot camping for gaming, OSX covers all I need perfectly yes I am aware there may be a new macro, and yes I am aware that I could just buy the Apple 5870, but I want to know about using a PC video card. Thanks in advance for your help. Cheers Anthony.
