Laptop

I'm going to college next week and am getting a laptop, which I would like to play FSX on, or at least FS9 with everything maxed. However, I'm having some difficult deciding what graphics card to get, as I'm not familial with laptop graphics cards. Any ideas? Also, is it worth getting the quad core as opposed to a duel core? I'll have 4+ GB of RAM (DDR3) and a Vista 64-bit OS.
