Asus or Alienware?

Alright I'll be buying a laptop soon and here's what I need it to do.

1. Play SWTOR
2. Play APB on atleast medium
3. Play Guild Wars 2
4. Play Diable 3

That is about it. I have pretty much narrowed it down to 2 laptops I am able to get.

I am able to get the alienware m11x with these specs

Intel® Core™2 Duo SU7300 1.3GHz (3MB Cache)
4GB Dual Channel DDR3 at 800MHz
160GB SATAII 5,400RPM
Bluetooth Module, 2.1+ Enhanced Data Rate
1GB NVIDIA® GeForce® GT 335M
11.6-inch WideHD 1366x768 (720p) WLED
Internal High-Definition Surround Sound Audio (5.1)
Alienware M11x a/b/g/n 2x2 MIMO Wireless
Integrated 10/100 Network Interface Card
1.3MP Web Cam

Or I can get this

I love asus products, I am unsure of the build quality of alienware, I would like this laptop to last me 2 years of most mmorpg's.

The only reason I am able to buy the alienware is due to the monthly payments option, 12 months if paid in full no interest.


Which would you choose and why? Thanks in advance
