Im in the market for a new highend system which i plan to overclock a little bit. Im aiming for 3ghz+. Recently i have been hearing rumors about the new C1 stepping that is to be realeased soon. My question is : What is so special about the C1 stepping? what proc speeds will use the new C1 and when will it be released? Apreciate any input.

They are out already, Intel Pentium 4 2.5GHz (NOT 2.53GHz), 2.6GHz, 2.66GHz and 2.8GHz all have this stepping. It's a more optimized version of Northwood core designed to hit 3GHz at the end of this year which many are achievingwith proper cooling today .

C1 Stepping Arrives:
In mid-august Intel announced the release of a new range of clock speeds for P4, around the same time they announced the 2.8GHz. What was interesting to note was that the core stepping had changed for some of the new line-up. Specifically it appears the some P4?s will now be fabricated using the C1 stepping, whereas all previous Northwood?s were B0.
