mmmmm, I was going to say Mac until you said Compatibility, lol. You can get a real nice HP, just load it up and get a 1 gig graphics card. If you are looking for the most power in a laptop Alienware is one of the only ones that puts dual GPUs in a laptop atm. I will say this....stay away from iBuypower computers, they have a lot of problems. Also, Dell and Toshiba aren't the best either. Sony Vaio's are fairly nice though you might pay just a tad more. It all depends on your budget in all honesty. Obviously you want a desktop replacement style laptop so you will spend a bit to get something good enough for all that.
