    I just installed the ATI 3870 in my macpro. The video speed!

    I also have an ATI 1900.

    Could both cards be installed at the same time?

    If something this werid is possible would there be any advantage?

    You might be able to have both cards installed at the same time (e.g., to run multiple monitors), but I'm sure you wouldn't be able to run them at the same time for any kind of performance gain, so I'm not sure what the point would be.

    I'm not sure how much power the Mac pro has to drive these cards. However if you can it won't make a difference unless you hook your monitors up to separate video cards as the Mac pro does not support Crossfire is OS X
