Actually the thinnest gaming laptop is the
Razer Blade Pro , which is .1" thinner than the Aorus x7.
However, the
MSI GE60 Apache is the way to go here. Although, you're going to want to spend the extra $50 and get the one I linked, as the $1199 model only has the Nvidia GeForce GTX 850M, rather than the 860M I just linked.
You get a lot more graphics power out of the GTX 860.
