    Best AFTERMARKET Card For Mac Pro 1;1
    Hi all, long time no se-

    SO I bought a Mac Pro 1;1, with x2 Xeon 5160 at 3GHz, but it has a Radeon X1900XT.

    So, I'd like to know what GPUs I could put in it?

    At this point, i'd be very interested in a HD 6870 1GB if that would work. Thanks!

    Lots of doubts about the 6870 in a Mac Pro 1.1:-

    Radeon 6870 confirmed working in Mac Pro 1,1 - MacRumors Forums

    In my M<ac Pro 2.1 days used a flashed ATI Radeon HD4870 with 1GB of memory no troubles at all ~ fast and rock solid. If interested PM me and I will advise the HK dealer.
    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!
