I'm debating the following issue in my mind:

I want to experiment overclocking on an Asus P2B 1.10 motherboard. My last foray into overclocking goes back to a Pentium 166MMX overclocked to 225MHz. My current CPU choices are a Celeron 333a and a PII 350 (both slot 1 processors).

Overclockers.com is reporting that the average overclocked speed for the Celeron is 487MHz while the PII is 465MHz.

Can anyone give me insight on why the Celeron appears to be better for this than the PII and which CPU will be most efficient while overclocked?
