Reviews for the Alienware M17xR4 3D GTX 680M
Source: Comp Reviews

Alienware's flagship gaming laptop has been updated internally to keep up with advances in graphics and processors but doesn't change its iconic design. Overall, the system really emphasizes style when compared to its competition. It doesn't have the same level of display, storage or graphics as its competitors at this price point but it makes up for it with a huge array of peripheral connectors, larger battery pack ad much more customization options.

Intel Core i7: The Intel Core i7 for laptops is based on the LG1156 Core i5/i7 CPU for desktops. The base clock speed of the CPUs is relatively low, but because of a huge Turbo mode, the cores can dynamically overclock to up to 3.2 GHz (920XM). Therefore, the CPU can be as fast as high clocked dual-core CPUs (using single threaded applications) but still offer the advantage of 4 cores. Because of the large TDP of 45 W / 55 W, the CPU is only intended for large laptops.

An Ivy Bridge-based quad-core processor clocked at 2.3 GHz with Turbo Boost support up to 3.3 GHz. Offers an integrated HD Graphics 4000 GPU running at 650-1100 MHz on a dual channel DDR3 memory controller.
