If you could find some GTX P106-100, just buy it. It's dedicated GPU for mining. Dont be scared, P106-100 with Hynix mem still has good hashrate: ~23Mh/s for Ethas and ~292sol/s for Equihash.
that still 10% less then same 1060 but with samsung memory
so this can be painful for newbie miners to know their new card is working not at full speed
but that is ok, do better trades and you will compensate a small loss of hashrate!
