I don't know what happened to you Rich!!! Never before you went to
Free Tibet would you have said such a thing. The Dalai Lama must have
injected you some nano-probes, so now you've been assimilated and
turned into "just one of these hippie guys". ;-))))))))))))

You should note that your comparison is not fair: your K6 uses 3dNow!
optimizations, when Intel CPUs don't have any kind of optimizations.
