I have a stock Mac Pro and Vista RTM but I can't get the video to work, I mean everything installs just fine, but the 7300GT will show up in the device manager but it will have a Code 12 error (the device can not find enough resources or something like that), I've tried everything, drivers will install but the video refuses to work, I have to deal with 800x600 and 4bit color, any ideas on what I can do?
