I have a 2008 MP which I ordered with the 8800 GT video card. I decided it was time to upgrade so ordered the nVidia GTX285 for the Mac from Amazon.com. Installed easy (didn't need the drivers as Snow Leopard already had them) except for the installation of the power cables on the MoBo (fat fingers need not apply ). So far I like it. I am waiting on Modern Warfare 2 so that will be a good test. It will be interesting to see how it handles the demands of Crysis2 when it ships after Christmas. The original game was very demanding (don't know why that was so as I just finished Far Cry 2 and the 8800 handled it easy and the graphics were just as good as Crysis).
