Re: "This means that top of the line chips won't over clock worth a darn. "

But they HAVE to overclock. There is a long term reliability issue involving the affects of hot electrons. All processors will degrade in performance over time due to voltage threshold shifts. To address this, manufacturers test their products at higher than rated speed, thus allowing for the degrade over time. Therefore, to be a 600MHz part it must run faster than 600MHz (I don't know the exact difference as it varies due to a number of factors). Neither Intel or AMD would ship parts that did not have speed margin. This is why I think Tom had to be doing something wrong. Compaq, IBM, HP, Dell, Gateway etc would not have accepted a part that didn't meet this quality requirement.
