Make no doubt about it – Alienware is king in the computer gaming world. Their machines cost a pretty buck but deliver top end gaming performance. The Alienware M15x is a vast improvement over previous generations: it’s 15.6″ screen has a shows high def in all it’s glory (1920 x 1080 resolution), it’s Core i7 720QM CPU scores ultra high on PCMark Vantage, and it’s video card scores above average compared to others in its class. The chassis is a little bulky and speaker quality somewhat sub par. At max settings battery life is limited to two hours. CNET gives the M15x 4 out of 5 stars because of the amazingly powerful CPU & Video card.
The top end tricked out system costs $3,199. If you’re a gamer looking for your next rig the M15x is worth every penny.
