Forget the globalwins! Get the newer copper sinks with the larger 70mm fans (80mm fans are even better if you can fit them).
The EverCool 715 & 725 copper sinks are great. They get larger as they go up from the CPU & spread the heat to the larger 70mm fan better.
Go to nexfan.com or casecooler.com for some of the newer cooling concepts. Your Video card may need some extra cooling too, as you creep the FSB speed further up to 100MHz & beyond.
I'll be comparing speeds between my (3) BP6 systems to see whether a single P-III @1.2GHz does much better than my slowest Dual-Cele1@466.
I also have a system with Cele2-1.1GHz @108FSB for comparison.
Results to be posted here soon.
Some of the Dual-Cele1 guys seem to think their systems run smoother with two slower CPUs than with a single 2x faster CPU. I'm skeptical.
