Compare i7-2960XM and i7-2860QM non-overclocked performance?

I am a novice trying to decide if the extra $700.00 for an “Extreme” mobile CPU – like the i7-2960XM compared to the i7-2860QM - will provide noticeable performance improvements (10-20%) in an off-the-shelf, non-overclocked laptop such as a Dell M6600 mobile workstation? As I understand it, the maximum thermal design power (TDP) of the 2960XM (55W) versus the 2860QM (45W) should allow the extreme processor to operate in turbo mode for longer periods without excessive heat causing the CPU to throttle back. True/False? And I assume that the higher clock multiplier (bus/core ratio; 27 for the 2960XM versus 25 for the 2860QM) will also add to performance even without overclocking the extreme chip, yes?

 

I have no interest in overclocking the laptop. Therefore, if the advantages of the “Extreme” CPU are only realized through overclocking, should I save my money and just purchase a standard CPU with the same (but locked) clock speed?
