I have had my M17x R4 since May 2012. This is my third and best laptop I have ever had. I'm fan of Total War games and Guild Wars 2 and this rig can handle anything that comes up. I keep this on a laptop cooler with a 220mm fan and the Alienware fans only really kick in on Shogun 2 when fighting with large armies. Which puts more stress on the cpu than the gpu. The differents in the rig reviewed here and mine is that I have the Ivy bridge 3820 cpu, AMD 7970, and the 32ssd and 750 gb hard drives. If you travel and like to play games and don't mine carring a extra 15 lbs around (adding backpack and other nic nacks) this is the way to go.
