I have 1060's and 1070's.  Getting about 18-19Mh/s out of the 1060's and around 28-29 from the 1070's.  

The key was finding the right mod for the miner and settling on the right intensity level.  Here is what I have learned...

1. There is very little you can do in the way of overclocking to get a better hashrate.  With Claymore and ETH mining, stock/overclock ratio can easily be 4/5.  Ie., 25 stock and 32 OC.  I cannot make ccminer budge with memory or base clock changes.  Power increase makes a small difference.

2. What ccminer reports as hashrate is NOT what you are going to get from the pool.  260 reported ends up about 200-210 from the pool.

3. The 32 bit ccminer runs better for me on Win10.  I have the version labeled ccminer_krnlx_170810.  There were three .exe files in my download.  The Cuda 7.5 32 bit version was the best of the three for me.

4. Compared to Claymore dual mining, ccminer is coming in at about 80% of the power when I think I have it fairly well optimized.  

5. Believe it or not, increasing the intensity MAY slow you down.  One of my rigs (5x1060's and 1x1070) runs great at i=22.5 and slows DOWN at i=23.

I was only able to mine for about 30 hours at the 5000 reward level.  I am going to mine this 100% for at least until it reaches 60K.

As for the current valuations, chances are very few people here have spent any time with financial markets and charts.  NEW things almost always dip multiple times before the market truly discovers and has confidence in a bottom.  That is why market tops and bottoms are almost never hairpin turns.  They have to work it out.  Lows are tested and retested sometimes many times before confidence is found and a march upwards begins.
