Hi Peter,

Well, your half right; I'm not developing the 3Dnow loops anymore since 
all CPUs
since the Athlon-XP/MP support SSE.

There have been some issues with SMP (multiprocessor) operation on 
Athlons using
LAM, so you might want to consider Intel Xeons for SMP if the price 
difference is small.
