So basically a gaming laptop? Any laptop you like with a 7970m then. That's the most powerful mobile gpu right now, and anything with that is going to be pretty damn high end. Get a cooling pad with it, I wouldn't game on laptop without one (the risk of overheating is just too high, or at the very least lowering the longevity of your machine with high temps)
And yeah, the two gpus to consider are the GT650 (Which is in the first few laptops I posted) for more portability and battery life and the AMD 7970m which is in the last few for sheer amazing performance.
