cpu usage in 7.0

I have a dual core system running 7.0 and I can't get
top to show more than 100% usage no matter how I
hammer it. My MAC shows over 100% often, but its not
clear if top is averaging the 2 cpus or just not going
over 100, or just showing 1 of the cpus.

Is there any way to show the per-cpu usage to get an
idea of the overall efficiency of sharing? Are there
any tools that can be used to monitor this? What
exactly is top showing?

Thanks,

Barney
