My computer has a CPU with 4 cores and 4GB RAM.

What I want is to find out, if I am using all the available power that my PC offers to me? How can I do this?

It is difficult to tell what you are asking, please try to be more clear. –  psusi Apr 28 '12 at 20:37
    
Are you asking if your PSU works at it's full potential all the time? –  Marius Balaban Apr 28 '12 at 20:49

Well, I do believe - actually - you're using not just your PC at its full potential, you're also wasting it!

  1. You've 4Gb of RAM, so 32 or 64 bits is the same. That's ok, you're correctly using all the available RAM.
  2. You have 4 cores. Ubuntu is surely using them correctly, because it IS made to use everything at the maximum.

The problem is (or at least may be), you don't want to use all the powerhorses all the time! Electricity costs.

If you do care about this point, install cpufrequtils and this http://www.webupd8.org/2011/07/cpu-frequency-scaling-indicator-fixed.html.

Otherwise, you're good to go!
