Nice Review as usual, but there is one thing I need to say. In the Graphics Card section of your article you say "Alienware's notebook scores only marginally, but nevertheless higher than Samsung's gamer.". You're referring to the Alienware notebook M17xR4 with the 7970M. The 7970M graphics card is 70% faster than the 675M in your Samsung notebook you have on review, I definately wouldn't call that 'marginally' faster, more like SIGNIFICANTLY faster! On this same topic, in the last paragraph of your article you refer to the Alienware M17xR4 with 7970M again, saying that it has only "slightly stronger Radeon graphics" for a few hundred euros more than your Samsung notebook; again, the 7970M is 70% faster than your notebook in review here, which is a HUGE difference at this level of performance, and well worth a few hundred euros in a high end gaming notebook.
In my opinion if you're going to buy a high end gaming notebook now, avoid the 675M (aka 580M), and get the 7970M, unless the notebook with the last generation 675M graphics card is SIGNIFICANTLY cheaper.
