No joke, get an Apple certified refurbed Retina display Macbook Pro. They have bangin video card options. My older 2011 non retina plays Skyrim like a mofo.
Get it direct from Apple and comes with a same as new warranty, has had any trouble parts replaced, and will save you some dough. Then just Bootcamp Windows onto it, which is wicked easy.

You'll prolly want more storage though.
The hardware is nice. The 650M you say plays Skyrim well? I was actually looking at a laptop with a GTX 780M. Unfortunately Mac doesn't work for me as I'm a windows platform developer. I will at some point be running a SQL server on the laptop. That and i'm a lazy fucker who likes everything to be ready and working on the laptop when I buy it.
Mac's do have good cooling though. Especially considering the thin style of their MacBooks.
