I own both. The major differences are that the Ultra 120 Extreme has six heatpipes (the non-Extreme version has four), and that the Extreme doesn't ship with S939 attachment hardware (in contrast, the non-Extreme doesn't ship with AM2 attachment hardware).
In terms of performance, they're very close. In my not-completely-scientific testing (as I have no way to either measure nor control ambient temperatures), the difference is maybe only 2-5 degrees C maximum improvement from the Extreme version. I've also lapped both, and strangely the temperature delta between the two remained consistent after lapping.
Is the Extreme version worth five extra dollars? Only you can answer that.
I think the differences in available mounting hardware would determine your choice.
Hope this helps!
