I suppose it depends on the game and at what resolution you want to play at. I had a laptop with an Intel HD 4000 for a very brief time. I decided to test a few games on it at 1600 x 900 resolution.
Dragon Age Origins - Playable.
Mass Effect 3 - Game crashes right after intro video??? It plays fine on my laptop using the older Intel HD 3000 graphics core.
Tomb Raider - Playable, but there are driver issues. "Black holes" floating by in a stream/river. Momentary stutter about every 30 minutes or so. Don't matter if it is an action sequence or if you are merely walking.
