I recently bought a mac pro, dual xeon. I know they are old machines but needed to upgrade and could no longer wait. My problem is the display card. I am using mac os for FCP and photoshop, and bootcamp for 3ds max. Have anyone really used the Sapphire 7950? I know autodesk push hard for quadro cards, but the only mac addition I can find is the k5000. Is it really worth the price?
