*sigh*
There is no doubt that the Opteron kicks @ss. There's also no doubt that the Opteron is hideously expensive and that AMD has RAISED the prices on existing models about 5% over the past month.
I was going to build a dual Opteron rig; I was waiting for prices to drop, AT ALL. Even a little!!
After two months of waiting, they went up. :Q
I purchased some very cheap, low-voltage 1.6GHz Xeons that are well-known to overclock to 2.6GHz at STOCK voltage.
While I've yet to give it a go myself, others that have purchased the same CPUs report very happy results...a dual 2.6GHz rig for under $500. That's the price of one Opteron 246. No mobo. No memory. No OTHER CPU to complete that whole "duallie thing."
I'm just disappointed, that's all.

Yes, a dual 246 rig will blow away a dual 2.6GHz Xeon rig...at about FIVE TIMES the price, it had better!
Sorry AMD, you screwed up. This is coming from someone who has FIVE rigs at home right now that they ALL run AMD CPUs.
