How much do laptop video cards cost?

I have a pretty poor one and trying to increase framerate of my Dragon Age game. Wondering how much does a decent one cost.|||You can't change out the video card of a laptop! Never have been able to, and probably never will be able to!|||you can't upgrade laptop video since it is the chipset/GPU soldered to the board only thing u can do is try to overclock it if you got a nVidia / ati chipset.|||Have you see any store that sell laptop video cards?
