Well, like many people in here I am faced with the option of buying either an old MBP or the new MB. So apart from the extra harddrive space (which I dont really need), the only spec difference I see is the graphics card. So between the old MBP's 8400M GT and the new macbook's 9400M, which is the better one? Considering the MBP in my case also has 256 MB of VRAM
