A few months ago I was testing an HD 6870 for my buddy and it had no trouble running either KotOR game.
That said, since this is for gaming, I would look into a laptop powered by one of the AMD APUs like an A8-3500M. CPU performance will be mediocre (but not bad), but graphics performance will be terrific for an integrated GPU.
