I hope some people with fast and slow computers will read this and will post
their benchmarks.
In particular we are very interested in benchmarks for the Athlon 600MHz and the
Athlon 1.2GHz.

That's something else. In my message I try to compute the difference in ELO
between singles and duals, given the compromises you have to do to in order to
get a dual.
