Alienware 18 Notebook: Haswell, GeForce GTX 780M
Battery Life
Other than a couple of outliers, the ASUS G74SX and the iBuypower Valkyrie, the Alienware 18 clocked in with a predictable 75 minutes of battery life which puts it on par and just a hair above most of the other systems in the group. However, considering that it's the only one with power-guzzling dual GPUs, that battery test is actually rather impressive.
