    Nobody argues that the PPC is faster in floating point. However for most 
    users, 99% of the time is spent in integer functions. Integer benchmarks 
    show that there is very little diffeence between the 2 processors (and 
    at least the x86 camp has a Pentium Pro to upgrade to today).


Don't know about the first, but I'll bet that factorials are calculated
using all integer ops.
