Remember when I made that thread about me getting a laptop for christmas? No? Well I'm getting a laptop for Christmas and I have done some more research and decided that I don't need an alienware. I noticed in my issue of PCGamer the Sager laptops so I looked them up. I customized one and heres the specs:

Sager N2180

Later I found an ASUS laptop that was roughly the same price with a slightly bigger screen, better graphics card, better processor, more hard drive space, and it looks better too!

Additional Hard Drive in Optical Drive Bay

What I'm looking to do with this laptop is mostly just play games. And by games I don't mean stuffty flash games. I mean fairly high demanding games such as: GTA IV, Mafia II, Crysis maybe, Source games, Fallout 3, Oblivion, Just Cause 2, Assassins Creed 2/Brotherhood when it comes out, and some other ones I can't think of.
Now a few questions:
1. Will these be able to run all, or at least most, of my games?
2. Do any of you have either of these models? If so, are they good?
3. The first costs $1113.96, and the second costs $1270.05. Is there a better laptop deal for this price than these model?
NOTE: I'm not looking for a desktop, I need a laptop. So don't suggest I get a desktop.
