This is true since the pipe to the memory grows with each added processor because of the built in memory controller. So the Opterons scale better.
After reading comments, I went to Tomshardware mentioned to see. It
seems, that the 2P configuration from Intel with Core Duo Xeons 5160 can
be now faster than 2P Opteron one; Intel did some architectural
improvements in order of FSB. So Peter, don't worry, Your choice has
been good, especially for the discounted price.

However it also seems, that in 4P config, Opteron leads again because of
Hypertransport vs FSB.
This is true since the pipe to the memory grows with each added processor because of the built in memory controller. So the Opterons scale better.
The value for the price can be also better with Opteron systems than
with Xeon, even in 2P config, because of both price of processors
itself, and FB-DIMM memory.
So, everyone be happy :o)
