Bad Company 2: i5 or Phenom II X4

i would go to Anadtech's CPU Chart and pull up a comparison of these two procs: http://anandtech.com/bench/CPU/2

 

here are your charts: http://anandtech.com/bench/Product/102?vs=109

 

i dunno, im pretty happy about being able to drop in a hexacore. I got my sys oc'd to 4.16 ghz and It runs like a champ. No i dont have two video cards but I convert videos constantly and trust me it's very very fast. even though the i5 may be faster. Dunno... But i'm happy with my AMD choice.
