I've been posting here about upgrades for my PC and I've been told multiple times that the Prescott core isn't very good for OC'ing. Funny I just read in the Maximum PC issue that it's a great overclocker, and just a few minutes ago I came across this: http://www.techspot.com/vb/showthread.php?threadid=15725 , a 3.6ghz p4 Prescott OC'd to 6009 Mhz. Holy...freaking...crap.
