Dual core here, It really shouldnt matter how many cores you have, for example: the game probably only knows how to handle two cores. You could have two-eight core proscessors(yes they make them) for a total of 16 cores and the game wouldnt care because it only sees two. The performance increase is a result of how powerful said cores are. If you had eight cores that are of the same type as the dual-core, the game wouldnt run any better or worse. Now if you had 16 gigs of RAM as opposed to 4 gigs, the game woudnt run better but not because of the proscesor, but because of the amount of memory. Then again, you could have 16gigs of ram but have an old Pentium2 proscssor and the game woudnt run. In short, the two are related, yet, not related
