It is to bad that you could not test an nVidia GTX card, one good GTX 780 would put all those to shame.
Actually, he can. The GTX780 can run at a low enough power draw that 5,1 Mac Pro should be able to power it. And it can be modified by MacVidCards so that it shows the Apple boot screen and works properly at PCI-E v2.0 speeds. I'd recommend to the OP to check the MacRumors forums, and look for the user named "MacVidCards". Or find him on EBay. His side business is modifying PC-based video cards such that they boot and work properly in Mac Pros. You can buy a new GTX780 through NewEgg or AMZN, and have it sent directly to him. He'll take it, modify it appropriately, and mail it directly to you.
All of that said, it won't beat the 6,1. ;-)
