Intel is slated to release next quarter a new P4 & chipset w/ an 800mhz FSB and dual channel DDR 400 support. If you can hold off, existing P4 533mhz and 845PE chipset prices should drop by a lot. (And the new stuff will of course offer even more performance.) I mention this b/c I bought a Dell right before the 440BX chipset came out. If I had had that mobo instead of the 440LX, I could have upgraded all the way up to a P3. I know there is always reason to wait, but with such an impending release, you're looking a potentiallly huge drop in prices for the existing P4 chips.
