Yep.....And that much I knew. When I bought this laptop a year ago, I wasn't even aware that dual cores existed. The thought of stacking never occurred to me. Now that I am getting back into thoroughly understanding that which I am building, I realize just how outdated my knowledge base is. At one time, I was the go-to guy for anything DOS related. That was many, many years ago....and I have forgotten it all. Well.....almost.
