Welp, decided that next year the main rig is going back to an Intel setup (may just nab an used chip, folks always tend to off load when newer chips drop).  Keeping the 1950X and it will be moved over to the 2nd rig and later upgraded when the new TRs drop (I really hope that bandwidth increase helps with CCXs and IFs speeds).  The 1900X will probably be sold off, and the mobo kept as a back up.
