Can you change laptop video cards?

I've got a vaio which came with a video card which can't handle large games, but i was told that it cant be changed. Is this true? Because I would like to buy a new one if I could.|||Probably not. about 5% of all laptops can do that. I think alienware and some asus are the only ones with video cards



Sony video cards are integrated into the motherboard. There is not a piece of hardware that can be replaced.|||No
