I have a 3.2 Northwood that does at least 3.7 on air. It's up for sale, PM me if you're interested.
seems the OP is asking about the CPU's not the motherboards..
Anything in the Northwood core category are gonna be the best since they run cool. The Prescotts got the 1mb cache on them but are ovens.

My bad ... I didn't realize until I saw the post about the 3.2 P4
2.4C's were known as the best overclockers, 3.2 - 3.4 Northwood or Prescott are fun since they can hit 4 and more if you have sufficient cooling.
I have a 3.2E that's been running at 4Ghz under water cooling since the day I bought it and is perfectly stable.
I agree with you on two counts.... 2.4C Northwood and Abit IC7-Max.

last I remember Abit IS7 (the cheaper version of the IC7) actually overclocked better......
P4 2.4 will nearly always hit 3.0Ghz (1GHZ FSB) or higher with the IS7 or IC7 with air cooling.
P4 3.2 will nearly always hit 3.6Ghz with IS7 or IC7 with air cooling.
P4 3.4 may or may not do too much at all in the way of overclocking.
My P4 3.2 Northy will overclock perfectly stable to 3.85 on air cooling with the Zalman copper flower cooler if it's winter time and it's cool in the computer room. During the summer I have to drop it to 3.6Ghz. This is on my Abit IS7.
It seems most of these chips and boards will have a real hard time getting over 3.6 - 3.8 territory stably with air cooling according to what I've read.
Based on the info above. You may hit the sweet spot with something like a 2.8 or so. That would make the 1Ghz FSB be ~3.5Ghz..... You want that FSB as fast as yu possibly can - towards 1GHZ FSB or faster if you can...The overall total increase in FSB/RAM/PROC and the ability to run the 1:1 ratio is probably more important than a smaller clock speed jump in FSB/RAM/overclock that comes with starting with the 3.4 and capping at that same 3.5 or 3.6 or even 3.7Ghz top.
These P4 C's had a 800mhz FSB stock, when you get it to 1Ghz. That's a 20% increase in memory and FSB speeds if you have DDR500 Ram (PC4000) you can run it at a 1:1 ratio. That thing will fly at that point. My memory speeds on my 2.4 P4 overclocked to 3.2 with the IS7 on my DDR500 at a 1:1 ratio are still faster than most everything available today according to SiSoft benchmarks.
