Is there a significant difference between the new nVidia 330m Graphics against the older 9600 cards found in the slightly older MacBook Pros (i am talking about both having 512RAM) not really bothered about the auto-switching deal as i will be Windows frequently for Gaming and using Snow Leopard for University work, oh and as a side note, will the i5/i7 make much difference when gaming (more specifically Modern Warfare 2 and Gears of War), Regards, skate71290
