Base system

The P4c might be a better chip to start with. They run a little cooler, and in most apps perform better to start.

The Crucial PC3200 might get you to a 225mhz FSB. Don't expect any more than that. Of course, if you start from 3.2 ghz that won't be too shabby at all.

PC3200 RAM won't get you too far with Intel unless you have a really fast processor to begin with (3.2C or 3.0C) and if you get one of those you kinda miss the point of overclocking - getting more for less. So AMD is your best choice - the A64 systems are good performers, but if you're looking for the max OC % the 2500+ MOBILE Barton rules the earth, AND you can still use that RAM and get great results. Also get some 1337 heatsink, though you probably won't even need it to get to 3200+ speeds (11x200). Also 1337 about MOBILE Bartons is their unlocked multiplier, search boards for why this is important.

Thanks for the advice so far. I think I will take to heart the advice to go with a non-prescott chip. Given the goal to have a HOT (pardon the pun) gaming machine I think the 3.0C is good advice given the limitations on the Crucial RAM. I'm not sold on the Mobo yet so keep the suggestions coming.
