A quad-core would be best, but I'm not sure how well a laptop will be able to get rid of all the heat. A cooling pad would also be a good idea.
General things to look for:
-Don't expect any kind of battery life or quiet operation
-Intel Core i3, or i5, or AMD Phenom II
-3GB RAM or more
Graphics, sound and screen size won't really matter. 32-bit vs 64-bit doesn't really matter that much either.
