My laptop right now has an 8600 gs which play any game I toss at it including Crysis with good settings, but I know it's going to get old soon. I enjoy gaming on my laptop, but if you have the room and don't move around a lot then a desktop is the better way to go. Just wanted to throw out my 2 cents.
