If apple do decide to use new graphic cards in the new mac pro, what kind of difference will there be to the current ones? I no nothing about the technical aspects of graphic cards and how exactly they work, but was just wondering if I will benefit from these new cards. I am in the process of setting up my own photography business and once up and running will be using PS CS3 and Aperture all day (along with Preview & DPP) What will these new cards do for me? I'm going to be upgrading from a PowerBook G4 so I'm obviously going to see a huge difference no matter what graphics card the machine has, I've just noticed a lot of people don't seem to like the current ones! Thanks in advanced for any feedback you have.
