Hey guys. I'm in the market for a decent gaming rig (by decent I mean running games like WoW on high settings with good FPS, and possibly games like Crysis). This is what I'm thinking about getting. I'm on a budget.

I know most of it is irrelevant but I didn't want to miss anything. So how would this handle lower end games like wow, and higher end games like Crysis?
Thanks a ton,
