I have 10 390x I am looking to sell. They are in good condition with all fans running. I have not modded the ROM's and run them at a slight overclock. I am building a large mining Rack and they just do not fit in with a bunch of 480's etc. I have original boxes for the Powercolor because they are watercooled but not for the Sapphire or Asus Strix
5 each - Powercolor 390x Devil - Watercooled $240 shipped CONUS
4 each - Sapphire Nitro 390x - $230 Shipped CONUS
1 each - ASUS Strix 390x - $230 Shipped CONUS
If Escrow is needed I will accept it using OGnasty
Here are pics of them mining XMR -
