Roughly $70 for a motherboard. Roughly $150 for a processor. Maybe around $20 for 4GB of ram. Excluding the graphics card, that should play PlanetSide 2 at the very least. Of course don't expect more than just barely making it with those. If you really want to play PlanetSide 2, you'll need to bump those up a couple notches. Of course only top end gaming PC's will truly play this game at a persistent 60fps or more, but that's not so much the fault of the gaming machines but the fact that the game still has a long way to go with optimizations.
:\ Sorry if I implied it was a requirement to have 32G Ram, I'm just usually doing homework and have a few browsers up while i'm playing.
