As it might have been said elsewhere, the second core may prove beneficial for playing/testing MP missions, if  you have to serve them yourself on the same computer. Then it might be faster to run a dedicated server (i.e. a separate thread) on the second core, rather than creating a multiplayer game from within the ARMA client. Those OFP:R users who have a dualcore CPUs should be able to correct me on this.
