Man o man how people get this wrong every time. The Canterwoods run 200MHz clock, 800MHz FSB -- if hes running 400MHz FSB then his clock is 100Mhz meaning he's not running a 3.4GHz chip -- minor technicality yes, but important technicality, yes as well
what makes it worth the extra $700 over a normal intel P4.
How about, its not a piece of crap like the Prescott? LOL nah Prescotts arent *that* bad -- they just didnt live up to (marketing) expectations, techie people knew for a long time that Prescotts werent all that fancy -- not until they are well into the 4GHz+ rang simply because of their insanely-long-crazy-pipeline
If you can afford the P4EE then go for it (or alternatively the FX53s)
