Drivers for the 8800GT were included as far back as OS X.5.2 from memory so you do not need to download anything. The power cable connected to the mother board okay as they can come loose? There are two versions of the 8800GT for Mac Pros, the 1st and 2nd generations. Got the correct one?

If still have that problem then the card may well be failing as graphic cards do. Also consider popping the 7300 into slot 4 rather than 3, as you can then set this up as 8 lane and slot three is only 4 lane.

On placing the card in slot 4 and on reboot, OpenGL should open and set it up as Option 3, 16 lasne slot 1, 1 lane slots 2 and 3 and 8 lane slot 4.

This explains it much better with graphics:-

Hang on to those original install discs like grim death! Using OS X.7 or later make a bootable USB thumb drive before running Installer!
