I'm in a similar boat. I planned to swap out my 1950x with the 39xxx series threadrippers and got bit by the socket change. The older i7 3930k was swapped out with a 3900x while we sorted the new hardware... and I'll be damned, but that AM4 CPU, paired with 4x16G sticks of RAM and an M2 drive has been a wonderful Linux workstation for development.
