My wife and I recently purchased an HP Media Center which has 2 intel Pentium processors running at 2.2 GHz (dual cores), 2 GB or RAM memory and an Nvidia GeForce 6200SE graphics card. We got it at a great price so we decided to dive in and replace our old Compaq. My question is, what is this dual core thing and how does it work? Is it that if I have one program running I'm getting 4.4 GHz? Any help would be great.
