Good free system activity monitors?

Hi Again All,

Does anyone know of any good free system activity monitoring tools either for the dashboard or bar?

I.E. one that shows CPU usage, Disk Usage, RAM usage etc?

Thanks,

Umm I've been using it forever and I never paid anything? >_>" Might be an older version...

The old free version, it must have a huge demand as it's a top download.

What's wrong with Activity Monitor, located in your Utility folder?

I bought istats menu 3 back when it came out. They ran a special and I got a 5 pack for $18. Nice upgrade but currently it costs $16 a pop. It is a little pricey.

There are also the istats dashboard widgets. I turned off dashboard but back when I was using it, I had this on there.
Apple - Downloads - Dashboard Widgets - iStat Pro

There is also geektool - but that will take more configuration
