New Semi-Gaming Laptop

Hey, I want to get a laptop that can be used for gaming. Portability, battery life, and looks are really big aspects of my choice. Performance is also a given as a requirement. I have narrowed my search down to the Razer Blade, the macbook pro 15 or 17 inch, or the msi gt683/5 with a gtx 570/580m. The msi will just blow away the other two in performance but it has a HUGE power brick and is super super thick. Any thoughts?
(I would like to play most of the newest games on mediumish to high settings)
