I'd tend to agree, and Kenneth also, it seems-- the raw FP performance 
of the P4s is kinda pokey compared to their int performance.  But 
whether that matters depends on what tasks you're doing.

OK.  The price difference for AMD vs. Intel is pretty significant, but 
be aware that you'll also pay a significant premium for dual-proc 
hardware versus single-proc machines: compare an AMD 2400MP versus the 
2400XP price, or the 2.4GHz Xeon P4 vs. a Northwood P4, and then factor 
in the additional costs for a MP-capable motherboard.

Are your machines especially busy, ie CPU-bound?  Two 2.4GHz processors 
is a lot of computing horsepower, although dynamic web content 
generation or virus scanning can be resource intensive if there's 
enough traffic...
