top can show per CPU usage.

While running top interactively, press the 1 key to show individual CPU 
stats.

top can also sort by a variety of methods.

While running interactively, press F to show the sort menu.

top can also be run in non interactive mode to collect data over time to 
a file, which can be used to create trend analysis.

You may want to take a close look at top.

Probably the best/easiest trend analysis tool is: munin, right now.

Good Luck!
