Hi all. I'm trying to buy a laptop for 3d animation (Blender), video editing, and gaming. I've narrowed it down to either an Alienware 17x with HD 4870 x 2, or an Asus G73JH-A2 with the new HD 5870. If they both have the same CPU and amounts of RAM, will I really see any performance improvement from the Alienware to justify its higher price? Thanks.
