Apple Ati Radeon Hd 5770 Graphics Upgrade Kit For Mac

I recently bought and installed the 5770 and it does not work. From what I read it would work in my Mac Pro 2,1. All I get is a lite up blank screen. The 5870 was what I really wanted to try but it wasn't available at the time. If 5770 won't work is there any chance the 5870 will. Or is there something I could try to get the 5770 to work.
This is my hardware.
