Can i upgrade my mac's video card?

I have a 15 inch macbook pro, with the intel core 2 duo 2.66 ghz, and geforce9400 and gefoorce9600 graphics card. It handles games just fine for now but this computer has to last me for a while, so is it possible to upgrade the graphics card on the macbook pro? I know the 9400 is like, attached to the motherboard or something, but is the 9600 upgradeable?|||No laptop ever made has had the capabilities of changing the video card! Where do people get the idea this is even possible?|||While the card inside the MBP is non-upgradable, there are indeed laptops that can have graphics cards updated. http://www.mxm-upgrade.com/ -- However, it's for PC based laptops that have compatible MXM slots.|||No, it isn't.|||Can't do it in a laptop
