Reviews for the Alienware M17x R3 GTX 580M i7-2820QM
Optimus Gaming. Nvidia GeForce GTX 580M graphics with Optimus, combined with a no less powerful Intel i7-2820QM quad-core CPU, all in a 17-inch Alienware Stealth Bomber case. Is it worth paying the extra for this top-of-the-range mobile graphics card from Nvidia?

The AlienWare M17x-R3 can carry out all types of task very rapidly. It also offers rich connectivity, a good finish and decent 2D and stereoscopic 3D gaming. While pricing isn't part of our rating criteria, this model will certainly be out of reach for many budgets. Those who can't get themselves an M17-R3 will no doubt go for a model like the Asus G74SX, which is less powerful but a lot more affordable.

The last incarnation of the Alienware M17x was dogged by feeble battery life and a high price. 5 hours of battery life under moderate usage, thanks in part to the said switchable graphics, was fine for a notebook with such high specs. To sum up, an extremely handsome notebook with stunning performance.

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.
