That Tualatin PIII was a really nice processor, and I've seen nothing but positive reviews on it. As I understand it, the PIII architecture had a lot more potential to it, but was largely dropped for P4 because it had a higher max speed/performance potential (now a reality). This certain processor tapped into some of that ignored potential.
It sounds like you've got it all worked out.
And yes ... this site (and just video in general) keeps me quite busy.
