I have two new 1070 and don't get the founders edition. Get one with 3 fans you will need them. Nothing stresses a graphics card like Iray or Octane. Bitcoin mining aside you need to make sure your new card and PC case have adequate cooling. Right now the best bang for buck is the 1070. I got a Black Friday Newegg Deal for the Zotac 1070 with 3 fan configuration for under $345.
