I agree, the Opterons seem to mop the floor with the Xeons due to simply being a better architecture, if nothing else. That said, I'm currently stuck with dual Xeon's for a million-entry directory and they still perform quite well -- consider carefully your price/performance and whether or not you'd actually use the Opteron's advantage. And as for the Sun thing, we've got a couple 40z's and I kind of wish we had waited, since they've now dropped that line (which as it turns out was basically just an OEM anyway) in favor of something "more-Sun." And Sun's always wishy-washy on their products anyway... FWIW, I've been quite happy with the HP DL585, too. Mmm... Opteron...
