Its the best option for me here @ local market. Sure there are cheaper options.
i see that on 80% you use 135 watts per card, so far 7 cards that would be around 945 watts. would it be possible to run this on a 1200 or 1300 watts psu, or is that not smart to do?
Oh OC is always worth it.
That 80% TDP bench is impressive.
Think you may have got me sold

Best card depends on two things, do you have not much room and lots of money and so want high density (for this Iād go for Radeon Pro Duo or GTX 1080ti) or do do you have loads of space and can do low density in which case the 7970 is by far the best card, 280 sols @ 180watts for $50. Set up a warehouse full of those and youāll be quids in!!
@zcrash
True, sure there are better cheaper options out there.
I live in a small apartment where electricity coats nothing (literally).
I just feel like every rig, every GPU can present problems, and the more rigs and more GPUs, more to worry about.
I want 3 or 4 very powerful rigs thatāll give me a good, solid income. Thatās why Iām not really talking about 480s, 1060s, etc. Iāve been waiting for Vega but it just keeps getting delayed and delayed, and Iām tired of waiting, I want a rig now and wanted to do a rig of 7 R9 Furyās but they went OOS. Now Iām looking at 1070s and 1080 Tiās, they seem as good for a higher price, but once the rig pays off the investment, itās a good income for a rig.
I needed the same thing carlosabia so I completely ignored RX series and went for Fury / Nano / Radeon Pro Duo / 1080ti.
Highest hashrate for minimum number of cards.
I got the Fury cards at good price jest before they went end of stock. If I was to do it now I would probably look at 1070/1080/1080ti as many as you can afford.

Haha weāre on the same boat. Us being and wanting the same, would you advise me to get 1070s or 1080 Tiās?
Is this just on Windows? Or Linux, too?
As far as i understood, the reason is the memory in those cards.
Again a driver issues, however there is a talk about an upcoming driver update that should fix the problem of low hashrate at least for Windows 10 that is expected sometime next month (we cannot confirm this however).
So the only thing that is left to do if you already got a GTX 1080 GPU or more than one and want to mine Ethereum with it is to go for Linux. Under Linux people are reporting about 23 MHS on average as hashrate for mining Ethereum on GTX 1080, a speed that is a bit higher than what you can get from GTX 970, GTX 980 or GTX 980 Ti, but still a bit disappointing compared to what you can get from high-end AMD GPUs.
OK, so back in June last year, mining ETH with 1080s on Windows was total crap, and Linux was somewhat crap. 
I wonder if this has changed with newer driversā¦
Nope

Damn, canāt believe how shitty the 1080 is for ETH. If you buy these you gotta marry ZEC, which itās okay, but you never know.

Always think that the āyou never knowā will happen 
Donāt buy a one trick pony card. I did it and i still regret it

Best Iāve got out of my 1080ti is 36mh. youād have to be a bit insane to mine eth with these cards given the difficulty. I switched to Zec full time back in March.
Getting almost 800 sol/s is a no brainer. Best ZEC GPU, right?
Yeah, i mine zec with them, just did a test for the thread.
Still, its good to know that the gpu will perform good in other algos when shi* hit the fan
Actually I think I made up my mind about making a rig with 1080 Tiās. Did some calculations and the investment gets paid off faster than with 1070ās. Iām between Zotac AMP!, Aorus and Gigabyte (Strix is like $70 more expensive and donāt know if itāll make a difference). Iām excited! Poor in the near future, but excited 
I only buy ti
but 1070s are great too
