I have 3 builds here and i can't decide which one is the best. what i'll be using the computer for is mostly school work, and some light gaming. Games like guild wars 2, assassins creed III. They don't have to play maxed out settings just medium-high. I'm looking for something that's cheap and something that i can maybe upgrade in a few months if i need to. I already have an optical drive so i don't need a new one.
