Historically, IINM, newer generation GTX x60 cards could never beat a previous generation GTX x80 cards. If 1060 could consistently beat a 980 in most games, that would be a surprise.
From the GTX1080 and GTX1070 reviews, it seems that Pascal with GPUBoost 3.0 will clocks higher than its rated boost clock, running at 1780 to 1800MHz most of the time.
GTX980 TFLops = 2048 x 1216 x 2 = 4.98 TFlops
GTX970 TFlops = 1664 x 1178 x 2 = 3.92 TFlops
GTX1060 TFlops = 1280 x 1800 x 2 = 4.6 TFlops (very similar to GTX980 perf)
Overclocked:-GTX980 = 2048 x 1450 x 2 = 5.94 TFlops (close to GTX980Ti, stock)
GTX970 = 1664 x 1450 x 2 = 4.83 TFlops (close to GTX980, stock)
GTX1060 = 1280 x 2050 x 2 = 5.25 TFlops
Using the TFlops comparison, this is IMO quite accurate indicator on how GP104 and GP106 will perform based on Maxwell. It is after all very similar layout. GP100's layout is somewhat different from GP104.
GTX1070 = 1920 x 1800 x 2 = 6.92 TFlops
GTX 980Ti = 2816 x 1075 x 2 = 6.05 TFlops
GTX TitanX = 3072 x 1075 x 2 = 6.60 TFlops
Hence, GTX1070 is faster than TitanX. But what happens when overclocked?
GTX1070 = 1920 x 2050 x 2 = 7.87 TFlops (only 14% increase)
GTX980Ti = 2816 x 1450 x 2 = 8.17 TFlops (35% increase

)
GTX980Ti once overclocked, will be faster, a bit
