Advice on Building a third Eth rig

[Dhodge87]

I cashed out just over $3,000 in eth when it hit $315 per recently.

I'm currently mining with the following
Asus 270-a prime with 9 1060 6gb cards with a 750w and 650w evga platinum PSU's
Older LGA775 gaming pc that was stripped of all raid and disc drives CPU downgraded from a quad extreme to a c2d that uses 40w. It's running 5x 1060 6gb cards on a single 750w evga PSU.
All cards are on the newer 006c sata-6pin risers
I'm currently paying $0.12/kWh.

All cards are currently running off of NVOC at a stable 23mh/s @75w

Now is it even viable to invest in building another rig?

Should I stick with the 1060 6gb cards that are currently $200-$250 per?
I've looked at getting 1070 cards but they are nearly double at 370-$425 per on eBay laey(I've bought a few this week)
Also are the RX cards viable now for the long run with the new bios fix?
Are the R9 290/390 cards still viable at 30mh/s.

I'm also debating about grabbing the asrock H110 BTC+ board as it's currently going for $120-$140 and moving the cards from my LGA775 board to it.

Any constructive advice would be great!

1070s are worth the additional cost imo. You can dual mine ETH at 32 MH/s and only draw 75W with the right settings. I also pay .12/KW and have found these to be the most flexible and power efficient across various algos.  If you're in it for the long haul might as well scoop up some 1070s, better resale value as well.

Could you please share the 75w setting? Thanks a lot

Not all 1070's can dual mine at that rate posted above. My best card is a Zotac and it hits 29 MH at 55%. All my other cards draw between 62-75% to dual mine at 28.4-29.0.

In my opinion, 6gb 1060's are the best option. At their price, you can't go wrong. You'll make all your money back and even if you sold the cards for dirt cheap you will come out ahead. Their electricity draw over an 8 card rig is 750 watts compared to 1160w for my 1070 rig. No brainer.

I was under the impression 1070 needed atleast 120w to be stable.

Same question here, how could get 1070 with 75w and 30mh/s?

So I'm looking at sticking with the 1060's and 1070's if I get them cheap enough.

Any thoughts on the boards?

Actually 31.3 MH/s ETH w/ 315 PASC per card at 79.5W to be precise. TDP is 150W right? I run it at 53% TDP.

So you aren't actually measuring the power at the wall, just doing some theoretical math?

Well its graded at 150W so I would assume 53% of that is 79.5.  At the wall is variable depending on the psu I use but it's around 80-90W.

It depends on the GPU.  Some 1070's can have 215w TDP but most are usually 150-170.  This is why we measure at the wall for accurate results.
