I bought an Asus G73S this last November and I love it. I would recommend you looking into it, or the G74 which is the next step up. It has taken everything I have thrown at it so far.
Specs of my G73S
CPU: Intel i7-2638QM Quad Core
RAM: 12GB DDR3
HDD: 500Gb x2
Vid: Nvidia Geforce GTX460 1.5Gb
17.3" screen and blu-ray
It came with only 1 500GB hard drive and 8GB of RAM.
