What alienware desktop can run crysis 2 the best?

I'm planning on getting a desktop for gaming and i want one which can run crysis 2 on max settings.

Preferably i want one bellow $1500.What alienware desktop can run crysis 2 the best?
Lets see my alienware m11x can run crysis pretty averagely like 30-49fps average. Sometimes it gets pretty low in some intense battles. But if the m11x can do that then most probably all of the desktops can run it pretty well. I also heard crysis 2 has lower requirements then crysis 1 but better graphics since of the new engine hope that helps. So no matter which desktop you pick they will all run it pretty nicelyWhat alienware desktop can run crysis 2 the best?
None of em, Alienwares look pretty nice but when you look real hard at the specs the RAM and CPU dont match up to the price. This is what I use, I play Crysis 1 and 2 on this and it seems to run it on highest settings without lag.

I'm sure all of em can run Crysis 2, but the most expensive one would most likely run it the best.
