My computer is fairly fast for what I do, but I can still slow it down by running several programs. I started running Tinyresmeter while running several things on my computer to see where my weaknesses were. It always shows the CPU usage maxed out before anything else. I currently have a 2.2 GHz AMD Athalon processor. I've been looking at some of the newer processors that fit my motherboard (939 socket). Would a 2.2 GHz dual core processor like this one be an improvement over the one I have? Is it really like having, 2 separate 2.2 GHz processors in one, or is this some sort of gimmick?
