Long gone are the days of gaming laptops being relegated to huge space heating blocks that were portable only in the loosest of terms. With advancements in mobile chips, manufacturers have been able to use higher performance chips that use less power and thus fit more ideally into smaller systems.Dell’s Alienware M14x starts with a 14-inch chassis that is a bit more substantial than your average thin & light at 1.49-inches thin and 6.45 lbs, but uses the extra size to stuff in some serious performance. Running the whole show is your choice of 3rd gen Intel Ivy Bridge processors, up to a quad-core Core i7.The heart of this laptop is gaming, so it wouldn’t be complete without some high graphics horsepower like the NVIDIA GeForce GT 650M, available with 1GB or 2GB of GDDR5 vRAM. Being a modern NVIDIA GPU, it of course has their Optimus automatic graphics switching technology. While graphics switching was hit or miss in its early iterations, these latest technologies result in seamless changes between GPUs that maximize battery life when you don’t need GPU horsepower.The usual set of features you expect in a premium laptop are also found on the M14x, like USB 3.0, Wireless-N, backlit keyboard, available SSD, and the like. The rest of the laptop is pure Alienware with its angular menacing design. LED lighting is abundant and fully customizable, allowing you to choose the light color for individual sections of the laptop, including the keyboard backlight.Being recently refreshed with Intel’s 3rd gen CPUs, we haven’t seen many discounts on this popular performance machine.
