The Lenovo Y510p is a pretty good choice, especially if you can get it with a decent discount. The single GT750M GDDR5 version is reasonably priced and gets about 5 hours on battery at idle. The dual GT750M SLI version is a couple hundred more but quite the performer for things that can run with SLI, getting it into the GT765 range of performance.
The Clevo W350ST
base machines are quite impressive as well and come with GT765M GPUs Note that from xotic windows is an OPTION so be sure to add that to the order if you need it.
The Asus N550JV is a DDR3 GT750M so not quite as good as the Lenovo but a little better put together and a much better sound system.
All three come with quite nice 1080p screens and the Lenovo and Asus have backlit keyboards.
If you want to go whole hog into gaming rigs look at the higher end stuff on xotic PC to get an idea. MSIs tend to be good value for money but are kind cheap feeling to me. Cooling wise the Lenovo, Asus and Clevo are all better than most MSIs. MSIs tend to make a LOT of heat and not exhaust it all that well. The Asus G75 series has excellent cooling but is a mediocre performer for it's price point.
My eldest son has a Lenovo Y500 with dual GT650Ms (GDDR5) And I own both an Asus N56VZ w/ a GT650M (DDR3) And an N56DP AMD 7730M machine. The N56DP is about the minimum to play MWLL fluidly and you'll have all the settings lowered and may have to run in 1600x900 for good frame rates on Enchaldas. The LEnovo and N56VZ are both 45+ fps on most maps and 30+ on the rest for me, at 1080p and either minimum or medium settings.
