XPS M1730 Custom Laptop?

I'm making my own custom laptop and just wanted a second opinion on whether or not this would be good enough to run todays games. You know like GTA IV, Crysis etc. Anyway if the specs looks good or if something should be tweaked please let me know. Oh, my friend has been bugging me to play WoW once I get this laptop. Would it be able to run WoW on like High Quality everything? Anyway here are the specs:
