Seems each SETI@Home unit is taking on average ~6400secs or 1.7hrs. And that's at 2.17GHz with 135MHz FSB. FSB should make a huge difference... or at least it did with the original S@H. I was very active in my S@H team's benchmark challenge and you could drop loads of time by upping the FSB. I had the lead until these P-Ms came out.
