Originally had a Mac Pro 2006 with a nvidia 7300. I added a 7800 gtx which worked fine with no updates or drivers needed. (it wasn't a mac version) Now that i've upgraded to a new Mac Pro 4,1 it has a GT120 from nvidia. I need to either get the GeForce 7800 or the GTX260 working. I've been researching and reading for almost 2 weeks now. I've tried everything I've seen and have had to reload this poor mac twice now. If all the drivers are built in, why does it only see the card as "Display" in the system profiler?
