I just got this http://www.digitalstormonline.com/co....asp?id=597328 .. it does what you want yours to do..5 WoWs at max res..in the city i was staying above 30FPS, all windows on ultra..if i started fraps video capture it went down to 20s.

With my main on max settings, and alts on fair with high view distance i stayed maxed FPS ( i have it set to max at 45FPS and 30FPS while capturing video with fraps.

Your rig is overkill for 5.. you could 10 box on that on high settings easy I'm sure.

My rig playes BF3 ..single player or multi on ultra with zero slow downs.. even in heavy combat areas. So your rig is future prrof 8)
