You know my first overclocked CPU was a 366 @550. That was when the top of the line CPU were PIII 500s. My celeron was the fastest chip in my dorm. My next CPU was a 566 @ 850. That was even more sweet. Although not quite as stable as the 550, It was a solid overall CPU. I mean My CPU jumped up 33% in performance just fom overclocking. It's too bad that I don't see anymore chips that have such a big headroom. It's seems like people are trying so hard to get their FSB over 140 and It's so rare to hear people doing 166 which sounds very natural. You knlow, it just isnt fun to overclok anymore.... SIGH>....
