If you're not going to use your laptop for intensive gaming then you don't need a high end laptop.
Besides, if you're a heavy user that battery will die within a year or two.
If you really want to go down the hardcore gamer route with a little KaW on the side.
You're better off making your own desktop pc.
But if it's specifically for KaW, a tablet or mobile device should suffice.
Or go and buy a $400 laptop, whatever.
