I'm in similar situation, going to enter college in a week and after weeks of researching, I have still not found the perfect laptop =(
Although, the MSI GS70 which just came out looks decent, is less than 6 pounds, and has a gtx 765m with a 17.3" fhd screen.
The Clevo W230ST is a nice little 13.3" fhd with a gtx 765m, although I've been hearing mediocre reviews and problems with that laptop.
The MSI ge40 and ge60 are nice laptops too, with a gtx 760 and 765m, 14" and 15.6" fhd displays.
The Razer Blade 14 looks great, love the design, but the screen is mediocre and the price is $500 more than it should be.
Other than those, you'll have to start looking at the 7+ pound 1.5" thick gaming laptops...
You pretty much have to make some compromises, whether in size or performance =(
I guess that's just life. Good luck.
