dual vs single core opteron 100's

I was getting into a discussion the other day about this and decided to
see what the FBSD amd64 gurus had to say about it. Given approximately
equal cost of, for example, a single core Opteron150 (2.4GHz) and a
dual core Opteron165 (1.8GHz) under what kind of situations would
one be preferred over the other?
fwiw- my friend asserts it will ALWAYS be the faster single core because
of context switches and dual cores are optimized for highly multi-
threaded OS's (e.g. WInblows). But 1) I think the scheduler has been
improved in 6.0, and 2) he's a linuxer.
And yes, I know what AMD has to say on this but am interested in the
FBSD community's perspective on this w.r.t. FBSD.
Q: Because it reverses the logical flow of conversation.
A: Why is putting a reply at the top of the message frowned upon?
