...Lol @ all the people in the thread telling OP to buy $1000+ laptop.
I use an Asus K53E. 673 bucks, runs it on all high at 60fps. Not Very high, mind you. And shadows are down.
Don't buy an Alienware, they're shoddy. Razer Blade will also be rather shoddy, although the thing is **** cool.
Stick with ASUS or Lenovo brands, they don't advertise much on their products and the installs are easy to clean up, and the build quality is good. Look for something with an i5 and at least 6 GB of ram if you want to max the game.
I would like to note that although I love my laptop, it needs a cooling pad for more than an hour of extended play, or it will cause lag. The wireless node is placed near the fan, which is a poor reason.
