I've been searching for a good & affordable ($750 at most, preferably in the $600 range) gaming laptop. It has to have a good CPU and graphics card that can handle games like Diablo 3 on medium settings (and guild wars 2 on at least minimum settings). I've been looking for a while now and am hoping to get some other opinions on what I should consider purchasing.
