It's interesting because the GTX 1060 is about 72% of the GTX 1070 but costs so much cheaper. Compare this to the GTX 960, which was 65% and relatively cost more expensive.
not 72%, a 1060 tested here did 1621 for a heaven 4.0 score. my own 1070 pushed 2634 clocked. even pushing a 1060 to 1800 clocked if it's possible means a 1070 is 46% more card and if 1800 isn't possible we're looking at a 62% gain over 1621

stock 970s did 1400-1430ish, moderately clocked was mid 15s
1060 is a great deal as it outperforms the 970 in every way and ties a 980 in many, it just isn't close to a 1070 by quite a lot. the 1070 is performing similar to the 980ti
