Hello, I am currently looking for a temporary solution to run a professional card, either Quadro or Firepro, in my Mac Pro to be used in Windows 7. The first question I have is would a Quadro 600 provide better performance inside of Maya and After Effects than a 5870? Would a Firepro V4900 be better than both? If one would be better, I will most likely be buying one fairly soon. However, would I need to do anything special when running OS X? Like disable a PCIe slot so OS X doesn't get confused or something like that? Also, would running one of these professional cards in addition to the 5870 under Windows 7 cause any problems? Thanks in advance for your help!
