Do I need to flash a Mac Pro 1,1 to get a ATI5870 to work?
thanks
No its replacing a NVIDIA 7300 GT 256 mb. in a 1,1. I just got a EVGA GeForce GTX 680 for my 5,1

It will work, but I've previously seen that on a 1,1 the performance improvement over a 5770 is very small, unless that has changed.
If you see data where the 5770 is identical to the 5870, then the issue is that it's CPU limited. It's not a question of PCIe bandwidth, it's simply that the app/driver can't feed enough work for the GPU for it to make a difference.
