Fastest p4 400mhz?

[dae_amp_ika_dtp]

hi. just wondering if anyone knows the fastest pentium 4 processor for a 400mhz system bus speed? im trying to upgrade an old pc to max out the cpu speed. currently it has a crappy celeron 2.1ghz @400mhz chip in it. just wondering if its even worth it? thanks.

--------------------------

nevermind i found it. its 2.6ghz. but would i see a huge improvement over the 2.1celeron? i also have a 2.4ghz p4 laying around, would it work, the fsb is 533mhz?

what kind of computer is it? If the motherboard only takes 400fsb, the 533 cpu will not work in that board. You would see a decent improvement over that celeron no matter what p4 you got:

Heres a Tom's chart comparing a celeron 2.4 and a p4 2.6:

go throught the available charts to see where they stand

thanks for thew info. i think i will be purchasing a 2.4 p4. its kind of hard to find the 2.6 for a decent price.
