turbo-boost

I have an Intel i7-3630QM processor in my laptop. Its speed is supposed to be from 2.4 to 3.4 GHz in turbo boost mode.

In reality, will it ever run all cores on full speed (3.4GHz mentioned above) at the same time?

I heard somewhere that this additional 1GHz is shared between all cores in laptops. If the boost is 1GHz per core it's pretty impressive (over 40% speed up). What does it really look like? How long can a processor run in turbo mode?
