Thank you very much for taking the time to read my question.
Nvidia off the shelf PC cards work fine with a few caveats. First, make sure you install the latest CUDA drivers from Nvidia before you install the card. Also be aware that your will not see a grey start up screen with the Apple logo, it will boot straight to the desktop.
I solved that issue since I have triple monitors. I have an older ATI Mac native card for one and the other two monitors are connected to my PC Nvidia card. SO in case I ever need to boot to CLI for example or use an Option key boot I can see the screen. Not sure what the power requirements are for the GTX680 so make sure the Mac Pro can support that.
Of course the Mac native 680 card won't have those issues so if you can afford that one it would work best, but if you want to save money and don't mind no start up screen I suggest EVGA.
