    i tried to do a search but didnt' have any luck

    has anyone here tried to use the stock 7300 vid card that came with the mac pro and run it with a nvidia 6800gt?

    i can't seem to be able to run both vid cards at the same time
    i have the 7300 on the top slot and the 6800gt on the bottom
    i have pcie power going to 6800gt and i know it works casue if i take out the 7300.. the video works

    so wondering if theres a setting i'm missing? or maybe can't be done?
    has to be 7300's only?

    also reason for this is planniong to buy a 3rd monitor
    and i have a dell collecting dust and it has the 6800gt inside thought i would use that to power the 3rd monitor

    also anyone know if Windows supports dual video cards?
