You could always go with the one with an 860m: http://www.newegg.com/Product/Product.aspx?Item=N82E16834317538
The 860m is faster than the m275x. Its basically a 750ti in a laptop. Also comes with an external dvd drive if you so happen to need it.

The cpu is better and the sli gpus work pretty well. I've heard a lot of good things about it and its cheaper.
