Specifically, if I overclock (and presumably overvolt) the cpu, does turbo boost behave differently?

Or, I hope, go into turbo regardless and leave it up to the user to ensure proper operation.
What is IntelÂ® Turbo Boost Technology and how does it work?
IntelÂ® Turbo Boost Technology is a way to automatically run the processor core faster than the marked frequency if the part is operating under power, temperature, and current specifications limits of the Thermal Design Power (TDP). This results in increased performance of both single and multi-threaded applications.
Which processor families support IntelÂ® Turbo Boost Technology?
IntelÂ® Coreâ„¢ i7 processors
IntelÂ® Coreâ„¢ i7 processor extreme edition
IntelÂ® Coreâ„¢i7 mobile processors
IntelÂ® Coreâ„¢i7 mobile processor extreme edition
IntelÂ® Coreâ„¢ i5 processors
What factors influence IntelÂ® Turbo Boost Technology operation?
While IntelÂ® Turbo Boost Technology availability is independent of the number of active cores, the operation is dependent on having headroom (cores operating under TDP) available in one or more cores. The amount of time the system spends in turbo boost will ultimately depend on workload, operating environment, and platform design.
How is IntelÂ® Turbo Boost Technology enabled or disabled?
IntelÂ® Turbo Boost Technology is usually enabled by default by a switch in the bios where you can either enable or disable operation. Other than this, there are no user controllable settings to change IntelÂ® Turbo Boost Technology operation either in the hardware settings or operating system. Once enabled, IntelÂ® Turbo Boost Technology works automatically under operating system control.
Is turbo frequency the same for all active cores in the processor?
Can IntelÂ® Turbo Boost Technology be enabled or disabled by core?
No. You can sometimes disable cores in the bios but this is not recommended unless there is a specific reason you need to do this.
Is there a way to specify the maximum IntelÂ® Turbo Boost Technology frequency?
There is no way to specify the maximum frequency. Once the system is in turbo boost, the processor automatically determines the maximum frequency it can operate at based on operating conditions.
What modes of operation are available with IntelÂ® Turbo Boost Technology for the IntelÂ® Coreâ„¢ i7-900 processor series?
1 bin (+133 MHz) across one active core
2 bins (+266 MHz) across one active core
1 bin (+133 MHz) across two active cores
1 bin (+133 MHz) across three active cores
1 bin (+ 133 MHz) across four active cores
What modes of operation are available with IntelÂ® Turbo Boost Technology for the IntelÂ® Coreâ„¢ i7-800 processor series and the IntelÂ® Coreâ„¢ i5-700 processor series?
The following chart shows the different modes of operation. Note that bin refers to a +133 MHz increase in frequency.
This is all I could muster up on Intel turbo boost. Lol! Dang I love to copy and paste.
