Q about memory and fsb

[Ninepepper]

I want to jump on a hot deal at best buy for (2) sticks of 512 crucial pc2100 ram.

My question concerns what is the maximum (non overclocked) fsb I can get with pc2100 ram?

I'm thinking of upgrading to the new p4s and chipsets with the 800 fsb, but will buying pc2100 at this time be a bad move and negate the advantage of an 800 fsb?

Thanks

The RAM will only officially run at 133MHz. The Crucial might run at 166MHz+, doubt it will run at 200MHz so you'd be running the RAM asynchronously to the FSB of the P4Cs.
