The performance degradation of the RXs is a serious blow for the mining farms that have it.
Loosing up to 35% of performance in 50 DAG epochs, or 7 months or so, is no kidding. AFAIK a DAG epoch is 100 hours long.
It looks like for now GP10x is the way it's meant to be mined.
The true winners are 1070 and 1060 6GB, but 1080 and 1080 Ti/ Titan XP are way under the max performance. That X in the VRAM must really hurt.

I agree about the missing hashrate/watt and hashrate/price charts, which are the most important data for profitability and ROI. But optimized OC and BIOS modding is very time consuming, risky and not consistent with different brands, versions.

Very good article, really informative and IMO should be part/continuation of the previous guide to Ethereum.
No benchmark on GM20x is a pity since many are bragging with the hashrate using the 347.88 drivers.
I hope you have data with power consumption like % TDP to calculate the efficiency for the hashrate/watt graph.
PS: There is a typo in the last chart, at the last two lines the value is 0.
