According to the diagram I have from AMD, there is a DDR controller
built into the Opteron itself.

Sure - if you remove one bottleneck, you discover another in the
chain. I suspect hard disc access will be the limiting factor on
these machines.

It's got to be the most accessible 64-bit chip, especially here since
the dollar is weak at the moment. A 200 series Opteron (the SMP
capable type) is no more expensive than a 32 bit P4, let alone a Xeon
or a G5. And of course Linux users have a head start since we can
compile native code or use an off the shelf AMD64 distribution.
