I am going to be starting college in fall 2013 as a computer science major. I do not care about computer weight, only battery life. I have about a budget of 2200$ give or take and I am interested in the MSI GT Series GT70 0NE-452. I have seen multiple reviews that it gets 5 hours+ of battery life. This would be ideal because I could always get a spare battery if needed, but 5 hours or more should easily get me through my day. Can anyone confirm this? I'll be waiting for the haswell processors to get my laptop, but I'm sure this will be a sidestep with upgraded components, but same battery life. Any other brands or suggestions of gaming computers that get at least 5 hours or more? I've also seen high battery life for the Sager NP9150.
