video card upgrade for older MacPro

[mamarazi]

i have a 2006 quadra core Xeon MacPro and the ATI Radeon X1900XT card that came with it has gotten corrupted -lines appear across the screen and I cant upgrade the firmware. I am looking to buy a new video card , either a replacement of the same or preferably one that is more powerful, but dont know which upgrades will work . thanks for any info bearing on this subject

The 5770 works fine in my 1,1.

4870 or 4890

I upgraded my 2006 1,1 MP from X1900 (which is under-performance than X1900XT) to 5770 and it's a blast!

I can finally play Starcraft 2 and Civilization V at highest settings :)

you might also want to try cleaning your x1900

4870 or 4890

To be fair, probably should not recommend 4890 unless we also make the readers aware that anything but an Apple branded card will likely require flashing. Flashing a video card may not be an option for everyone.

All that said, the Apple 4870 works perfectly well in a MacPro1,1 though it is expensive. I installed it on a 2006 MacPro without issues, and it provides vastly improved performance. It is also a lot quieter than the old 1900 I replaced. Others have reported that the Apple 5870 works in an older Mac Pro as well, but I have not tried this myself.
