Neither would be my first choice, but the Alienware 14 just seems better. The 765m offers most of the performance of 750m SLI without the headaches, the Alienware has a decent 1080p IPS screen, superior warranty and sturdiness, manual GPU switching, etc. If you can get a good discount on the 14, consider it.
The Clevo w230st and Clevo/MSI 15-inch "gaming laptops" offer more bang-for-the-buck than both.
