    Have a 2008 Mac Pro, Model 3,1. Came with the Nvidia 8800GT 512mb PCIe graphics card.

    I think the card is going bad. When I try to load up a game, the machine freezes. On reboot I see the typical green stripes/lines, as well as artifacts. If I let the card cool it works fine in OS X. But anything graphic intensive causes a crash. Sounds like the video card, right?

    Assuming it is the card, what are my options? Can I put the Nvdia GT 120 card in this 2008 3,1 Mac Pro? Is the GT 120 as good, or better, than the 8800 GT? Or should I just get another 8800 GT?

    Any other cards I should look at?

    Finally, is it an easy replacement? Do the replacement cards for Mac Pros come with driver software?

    Asking because I've never done a video card upgrade on a Mac, only PC.

    Annoyed my 8800 GT is failing, but I'm not under warranty, so any input is appreciated.

    That happened to my 8800 GT as well (and a lot of others, so I've heard). I wouldn't bother with a GT 120 - your 8800 was far better. You can get the 4870 or GTX 285 that Apple and EVGA offer, or you can flash yourself a PC 4870 or 4890. I have a 4890 in my machine now.
