I am assuming you are talking about the difference in the version of Windows? I don't think that will make too big of a difference. However something that did not even notice before is that my memory is almost 400MHz faster than his so I know that is part of it, just not sure how much exactly. I am really not sure why you would run the NB that slow to begin with. I don't think it would give that much of an increase in overclock for the CPU, but I could be wrong.
