I think the game uses the CPU more than most games I have played recently and might make really good use of multicores. The game was running amazingly well for me to the point I had to keep rechecking to make sure the opening cut scene was not pre rendered. I have the same cpu that you have or the next step up both of which are 8 core I believe but my video card is pretty long in the tooth a gtx 660. The game defaulted to most everything being set to High and I mostly tried running with the defaults as a goof and it worked.
