Hello Jay,

Seems like pretty fast system! About the Rebel benchmark, there are only 7
rating points between an Athlon 650 and a Kryotech Athlon 1000 MHz but that is
maybe an artifact of the used formula at these high speeds? Just a guess. The
solution times and NPS probably are more significant, you can check that for
yourself, the rating result seems to be about what you would expect. Did you
enter your result for the benchpage? http://www.rebel.nl/bench.htm Your machine
is listed among the possible entries.

Regards, Eelco.
