I got a toshiba laptop. (Satellite series L655D- S5050) which has an ATI HD 4200 laptop graphics card. I can play source games fine on it (Team Fortress 2 (choppy at 1080p though), Counter Strike: Source), I also can play far cry 2 at 720p (Low Settings can "run" at 1080p).
The one game I cannot play that I have is Battlefield Bad Company 2. It's dying even at xga settings on low.
I'm not sure how I got through the beginning of it. Funny my lappy outspecs the xbox 360 yet the xbox 360 versions runs like a hgih powered gaming rig.
