Requesting Gaming Computer Advice

[FR4NOx]

OK, so I figured if I sold my laptop I would be able to get a better computer, and simplify it by having all of my files on one computer, and i can take the power with me.

I'm looking at these two Sager laptops, one's a 11.6" and one's a 15.6". The major difference between the two is the graphics card, and mobility.

Or I could upgrade to this one, with a better graphics card and I believe the ability to ugrade the GPU at a later time:

All of these are going to have the base 3rd gen i7.

I'd like to keep it around $1000, cheaper is better. I can pay more, but I just want to get what's reccomended.

I don't have time post much, I'll add more later.
