The systems which I referred to were single Opterons.

Only the 2xx and 8xx Opterons. The (cheap) 1xx Opterons
are for single-CPU systems.
_If_ I buy an Opteron system (which I'm currently not sure
about), it'll be a single-CPU system. That's already
expensive enough, and I don't need that much CPU power,
so why waste money on a second processor?

I don't want to. I'm just making observations and try to
find some sense in them. :-)
