Will this system handle 5 boxing? I plan to upgrade to 12 gigs of ram. Also when I say handle meaning dalaran wont be a lagfest. I would like to still be able to run 5 through dalaran and stay above 20-30 fps just dont wanna buy a pc then fine out it can only handle 3 or so if you know what I mean.
