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. >> ...although the spec2000fp numbers are 641 vs. 726, so the Xeon does >> better at floating point. For that particular test, anyway.

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... -- -Chuck
