But I'm not sure what would fit.|||no|||Unfortunately one of the flaws of a lap top computer is that you cannot easily upgrade a video card on them. This is because a laptop graphics processor is built directly into the motherboard of the lap top. In order to upgrade the video you would have to fully replace the motherboard (not easily done because they are not sold at most retail stores or internet stores) The laptop itself sounds pretty old, you could probably upgrade to a whole new set up that is faster than that for only around 400-500 dollars.
