5770 in a Mac Pro 1,1

[ashman70]

How big of a deal performance wise is it that a Mac Pro 1,1 only has PCIE 1.0 slots? Is it a waste to put a newer card in a Mac Pro 1,1 because of this? Will the performance be significantly less? I ask because I am going to be upgrading a Mac Pro 1,1 with quad core CPU's and a 5770 video card.

It may not quite be as fast in a 1,1 but it's still plenty quick. I can run Starcraft 2 @ 1920x1080 pretty much maxed out without difficulty. If you intend to keep the machine I don't think you can justify not upgrading it at this point ;-)
