My current laptop runs this on max @60 fps, only time it dropped to 40 was during behemoth pop @ coerthas with hundreds of people flocking over like mad men lol.

Setup includes
i7 3rd gen
16gb ram
256gb ssd + 1 tbh storage
7970m x2 in crossfire.

With all that said, it IS portable and I do travel with it but it isn't as light as my wife's chromebook so don't think u'll be playing in the park :P

Out the door u're lookin at $1900-2k ballpark if you go with Sager, which is what I have, and a few hundreds more if you go with alienware.
