Mafia 2 doesnt work, it gives inconsistant results, you will find yourself gaing or loosing score with every run you do. Thats why they dont bench it in reviews anymore;).
Since you have 560 and shant has 460 then its obvious who is gona win, its you AVO. Dont under stimate the i3s buddy ;).
Here read this review its between i7 and i3 at the same speeds:

Also AvoK did you manage to oc the 560 yet? And Shant if you read this what is your oc on your 460? And what is it?
Edit: Saw his system, Avo i3s are faster than every quad out there with the exeption of "highly oc-ed" q9650 and q9550...
If anything this should be a race between OCs of my Msi and his evga ;).
