will ATI Radeon 5770 work properly in a 2007 Mac Pro 1.1 Dual Core Intel Xeon 2.66 GHz, 2 GB memory operating 2 Apple 20" displays? Presently has NVIDIA GeForce 7300 GT in one PCI slot with 3 empty available. Need more capability to operate X-Plane flight simulator properly.
This thread may be of interest. I haven't read all of the comments in detail, but what I got from it was: You can run a 5770 on a 2007 Mac Pro (it has to be the Apple one, not a PC one).
It will only support one monitor.
You need to be running 10.6.4 or higher.But read through it yourself as I may have misunderstood what people were saying.
