Depends what you are doing with the chip, for heavy multi-thread workloads, production software, obviously it would be worth it. From a pure overclocking or gaming perspective, I would say no.
My personal issues with the 3900 are as follows:
Harder to keep cool, we see already how the scaling is directly effected by temperature.
The surface area to cooler gets saturated even with the best of water-blocks, that is a lot of cores in a small package, it's not Threadripper size.
The chip very likely already has some weak silicon, or those chips would be in the 3950 bin. Granted the weak ones are disabled, but it makes me assume less headroom above and beyond.
Uses a pretty fair amount more power in every respect, VRM, motherboard, CPU, for no net gain for my use case.
A little bit of an unknown factor regarding latency and proper software instructions for using 2 CCD's
The one nice gain is the doubling of the cache, but again in "normal" use I am not sure how much a gain that is, considering AMD didn't seem to skimp on the cache with any of the 3000 series. The net effect may turn out to be zero, because the cache is the same per CCD. Don't get me wrong, if you have a use case for the 3900, spend the extra. I just don't, 16 threads as fast as I can get them is my ideal scenario and I thought the 3800 is the best candidate.
