upgrading the graphics card to a GeForce 7950 GX2

No. Only the video cards available from Apple have the EFI boot ROMs needed to work with OS X. Standard PC cards will only work if you boot into Windows (and have the appropriate Windows drivers installed.)

Hi. Please excuse a good deal of niavety I have on the Video Cards subject.. I had the same question (but for Geforce 7900 GT). I have major hope for Apple to be able to do this!! One thing I read from the Nvidia.. does seem to refer to it as a PC card: Designed for extreme HD gaming, the NVIDIA® SLI™-Ready GeForce® 7900 graphics processing units (GPUs) deliver the most graphics performance bang for your buck, including ultra-realistic gaming experiences and resolutions up to 2560x1600. A 256-bit memory interface and fast GDDR3 memory enable blazing graphics performance with maximum quality so you don’t have to choose between frame rates and image quality.

Need a break from gaming? The GeForce 7900 GPU also delivers smooth, high-definition video playback and crisp picture quality thanks to its advanced NVIDIA® PureVideo™ technology.

If you are searching for an extreme HD gaming and video experience on the PC, look no further than a GeForce 7900 GPU.

Available Models: GeForce 7900 GTX, GeForce 7900 GT, and 7900 GS


but 3 pieces of information say that it can be used on Mac OS X.. I don't know you seemed to have said it is like a third-party something but the Mac Pro I am looking at is at ?Geforce 7300... so I would find it hard to see why this wouldn't be an Apple card, a PC one instead. This is REALLY important to me! here's one link fron the major NVidia site: http://www.nvidia.com/object/7seriestechspecs.html
