Thanx for the input. I did not know the TPC website, that's very helpful. Ans also the Opteron option i will look at. I am convinced that you should not use that kind of " rule of thumbs" and more important, my colleague is now too...

But I do know some HW guys. The common nickname for Itanium is 'Itanic'

Make of it what you will.

The current IO champ in price/performance is not Intel, but AMD Opteron.

Don't know if it has been through TPC, but I do know some folks that understand IO and CPU's down to the bit level, and their choice is Opteron. I believe HP has
a line of servers with this chip.

Very fast with Oracle.

FWIW I ran Kevin Closson's "silly little benchmark" on some Opteron 8218XE's and Xeon L5320's a couple months ago -- and the Opterons cleaned house. Kevin had a series about the Opterons too. I completely agree that they're very good processors.

I've also heard that the Itaniums aren't that great, although I don't have any personal experience. They do seem to have lower priority for receiving Oracle patches and support and such. I was just pointing to the TPC website because it might be useful in trying to persuade a manager to consider Intel alongside IBM. :)
