My experience:
1. Top is reporting that root running Xorg takes 24% of CPU.

2. Start System Monitor on processes,
Top reports Xorg 30%, gnome-system-mo 7%.

3. I press System Monitor Resources tab, and top shows Xorg 53%, gnome-system-mo 9%.

So the System Monitor Resources tab takes (53 + 9 - 24) = 38% of CPU resources.

Minimising System Monitor makes no difference to top.

4. Edit, Preferences, Resources, "Update interval in seconds" is set to 1, but it is clearly updating much more quickly than that. Changing to "15 seconds" slows the update to about 1 second, and top reports Xorg 24%, gnome-system-mo 1%. Change "Update interval" to "30", and it updates every 2 seconds, with no great effect on top's reports.

My conclusion: the System Monitor Resourses update interval is broken, and should generally be set to 15.

Note: all top numbers given here are after the system has settled down.
