Moved to a 3900x about 3months ago - was running a 5820k which I had owned since new. Began it running stock but had it running at 4.2 without any issues for a year or two before as a final 'go' I clocked it to 4.6 which it ran very comfortably and cooly till I sold it.
It was installed in a custom loop and heat was never a problem.
Would not hesitate to recomend (assuming that you can get one that clocks reasonably!).
I changed and moved to AMD for a number of reasons:-
1. Fed up of Intel prices.
2. AMD had , suddenly , become competetive and prices were much more to my liking.
3. Boredom - fancied a change
4. Could see the need for more cores in the future.
Summary - it is easy to convince oneself of anything if you really want to do something !!
Is my new system quicker - yes (but not by that much!! )- factoring in the cost of new chip,motherboard (x570),ram (3600 from 2666), case FD R6 , 1 x 512gb nvme , 1 x 1gd nvme etc it was an expensive operation !! (but it looks great

)
Would I recomend the change 'up' to anyone else - tbh NO (it was I think an excellent system and would have lasted for a few years yet).
