You aren't going to see a difference...
As far as the CPU goes, 3.2 GHz is 3.2 GHz. Regardless of anything else. Will put out the same heat and need the same voltage.
As far as the board, the NB will need more voltage (possibly) and get hotter.
The tangible differences are irrelevent in all but synthetic benchmarks. Perhaps you'd see a 1% performance increase in games, but it isn't going to be noticeable.
