Hi! I'd like to upgrade gpu on Mac Pro 1.1... What graphic card can I buy without suffer PCIe 1.1 bottleneck? I was thinking about HD6870... And I've read that it is compatible on my Mac Pro... Need I flash this card? Or does it work out of the box? Is this compatible with Mountain Lion? Thanks! Smiley

TBH I wouldn't worry about it.  What are you going to use it for?  Gaming, photo/video work, something else?  I was using a GTX 560 Ti for several months before I even heard about the PCIe Gen 1 issue with non-EFI cards, and it ran like a champion for stuff like WoW and SC2 etc.

Any modern card is just going to destroy the officially supported cards for the Mac Pro 1,1 even with the PCIe Gen 1 limitation.  You'll probably only notice a difference in directed tests like CUDA-Z or something.

Another question: is GTX560 going to work out of the box? Need I install some nVidia drivers?

I barely found some information about gtx560 on Mac Pro 1.1...
Here:
http://forums.macrumors.com/showthread.php?t=1325709
for example, says that gtx560ti is supported ootb... Works only except boot (this could be a little problem since I'd like to dual boot this Mac)... But don't know if gtx560 works natively...
