Meter for Intel Turbo frequency

I have a laptop with Core i7 2630QM (Base freq 2GHz TurboBoost2 upto 2.9 GHz).

I was always curious about to view the dynamic overclocking that occurs in i-series when it is subjected to heavy loads.

Initially I tried Intel Turbo boost monitor. It shows single bar for current clock frequency and doesnt look cool.

1. My doubt is that whether the dynamic overclocking occurs for all cores together or each core is dynamically overclocked at different frequencies as needed.

   So if different cores are actually overclocked at different frequency then why Intel's Turbo boost monitor shows single graph.

   Now my favorite gadget All Cpu Meter is updated to show turbo boost.

   However I cant find it very well.

   Check this image:

2. Does the increase in clock frequency above the base clock is the only way this gadget shows the turbo boost?If yes then again they are showing the single textual increase in frequency value as turbo boost.

3. Is there any better tool.
