I have a Mac Pro with Two 3.0Ghz Quad-core processors, plus 8GB of RAM and a 30 inch Cinama display. I am using a ATA Kona 3 card for my video output and Capture with FCP. My current graphics card is the Nvidea GeForce 7300 and needless to say, I'd like to upgrade asap. What is is the best video for running After FX, Motion, FCP, and possibly Maya on my system? I hate slow frame rate playback so I'd like to get the most robust card for the system. Right now I am trying to decide between the ATI X1900 XT and the NVidea Quadro FX 4500. Does anyone out there have experience with either of those cards on a system like mine? If there is another card I should be considering, please let me know about it as well.
