I've been on quite a journey.

My end goal is to have XP recognize my two ATI Cards (HD 5800 & 9800 XT).

What I've gotten so far is if I remove One of the cards I can install the appropriate Driver (HD 5800).

However when I plug the second card in and boot up I get an error saying the ATI Driver is not installed and neither card is recongnized.

Device manage doesn't even shoe the VGA compatible device.

 

So, is there a way to either get both cards running OR have it toally ignore the second card/display so I can still have the machine see that I have the HD 5800?

 

I'm going bald from all the head scratching.

 

Thanks in advance

    The Mac Pro workstation last model was 5,1.

     

    Why would you want a 2nd ATI card anyway that is that old.

     

    The other thing, my nVidia 9800GTX requires power and a Mac Pro only has enough to power the 5800.

     

    Besides, you want to use a Mac Pro, and use your system, you will need Windows 7 x64.

    OK, My bad. Its 1,1.

    How I got to this point as far as hardware.

    the MacPro came with the 9800XT.

    I bought an apple cinema Display with mini display port.

    I then bought the HD5800.

     

    I'm happy with what I have it works great in 10.6.7

     

    That said my question still stands, I think.

     

    Will XP simply not allow me to use these two cards?

     

    Will windows 7 x64?

     

    This is a simple matter of because its there and the ability to fire up steam and play the games my buddies are.
