now dilemma in choosing GTX 1060 or GTX 1070. Preferable Asus or Zotac. Any problems with Zotac card ?

My PC is connected to TV (Full HD TV) as I don't have monitor. Game that I would like to play are like Call Of Duty, Need For Speed, Forza, Batman Arkham Knight, Battlefield. Oh ya, using i7700K with Corsair 16GB 3200mhz RAM

Still using old Power Supply CM Silent Pro 700W. Connector which connect to PSU is only 6 pins while the other end is 2 x 6+2-Pin

Please give some comments.

Thanks.

GTX 1060 not support SLI
