As an the 3950x without a clear need, I would not recommend it. It is interesting that in some loads, the processor can give out 4.5 GHz to all cores :D Now let's talk about overclocking and PBO, to be honest I don't see the point in this action for this stone. He himself in default (plugged in and turned on) is boosted almost to 5GHz. And yet still hot. So I didn't even try it.
