Alienware M11x or Alienware M15x?

The m11x has a better graphics card but the m15x has a better processor. Unless you need the portability and battery life of the m11x I'd get the m15x. Except that I would get a less expensive processor and a better graphics card (that is if you intend you use your laptop for gaming which I ume you will). The i3 processor in the m15x will be faster than the ULV processor in the m11x and then you can get the awesome GTX 260M graphics card. Plus this configuration should be $100 cheaper than the m15x you configured.
