I'm sceptical about that, but regardless I'm looking at getting the successor to the 1060 to finally replace my old 670.
So am I. Some people came to that conclusion since the alleged 3D Mark score of a leaked 2060 was comparable to that of the 1080. Although it wouldn't be the first time such a jump happened. If I remember correctly the 660 was comparable to the 580 when it released.
