Hi Steve!
> Any pointers?
Nicolas Calimet has written a pretty detailed article which compares
different compiler options for POV-Ray on different hardware
configurations running linux. There's an Opteron in there, too, although
it's a 246, not a 800. But perhaps the informations in the text apply to
your case, too. You can find the article here:
