Hello!
Can anyone tell me what will be better for mining 1070,1070TI,1080 given the "price/mining performance/power consumption" ratio?
And which GPU version (SC, SC2, FTW) should prefer?

1070 i would assume is still best on this list but i do not know enough about the 1070ti to know if its better than the 1070. as for the exact model, i would go with the cheapest dual fan design you can get your hands on. highest clock speeds are kinda meaningless when you constrain the power limit to only 60% to get the best power efficiencies.

If you want a stand alone rig that does mining the more GPUs the better.

1070Ti has the same hashing power as a 1070.  Not worth it.  Best bang for your buck depends on what you're mining.  Best ROI cards are AMD 570's.  They are the kings of ROI (100 days or less kings of ETH and with it flying what you mine today might be worth more tomorrow).  Your next best bet is actually Vega 56, as they can do almost 4 bucks a day on Monero (120 days).  1070 cards are the king of power misers (150+ days), that's about it.  Even a 1050ti will take almost 170 days to ROI.

1070 ti has quite a bit more hashing power ON MOST NVidia FRIENDLY ALGORITHMS than the 1070 does - ETH is NOT an algorithm you should even be looking at with a 1070 1070 ti or 1080 now that AMD pricing has dropped back close to reasonable.
Even the 1060 is starting to look like a "iffy" choice for ETH mining given current pricing levels.
 
 1070 ti efficiency is the top on algorithms like ZEC when run at the most efficient point for the cards, though the 1080 can almost match it and the 1070 is close - but the "most efficient point" for the 1080 and 1070 ti is also having the 1080 give nearly identical hashrates, making the 1070 ti a far better choice on a hash/$ basis at that operating point.
 The 1080 gets higher hashrates if you run the power up to higher TDP than the 1070 ti, but that hurts efficiency a lot on both cards.
 
 The days of 3-4 month ROI are long gone (possible exception *IF* you can get a VEGA at somewhere near MSRP and mine Monero on it - but VEGA is not as good as other choices on a hash/$ basis on anything else so it's VERY dependent on Monero).
 Even at current pricing on the RX 570/580 they are NOT seeing 100 day ROI - more like 200 - even with the recent price rise on ETH.

The EVGA 1070Ti FTW2 requires two 8-pin power cable. The 1070Ti SC only requires one 8-pin connection. So you need twice as many cables or splitters. The FTW2 also has a higher wattage that you may need to account for.
Odd though how my 1080Ti only needs an 8 and a 6 pin..

they add the extra power for overclockers and to make the card look more powerful. it really serves 0 practical uses to put dual 8 pin on the card.

Dual 8 pin on a 1080 ti at the high end the Aorus Duke and FTW models makes some sense - on anything less it's dumb.
 
Single 8 = 150 watts then add in the 75 watts from the bus = 225 watts which is overkill for ANY 1070 and leaves a fair bit of room for the 1070 ti and 1080.
8 + 6 would be 225 + 75 watts = total of 300 watts, which might make sense for a top-end 1080 or 1070 ti, is SERIOUS OVERKILL for anything less than a 1070 ti, and leaves a LITTLE push room for the 1080 ti but not a ton of it.
8 + 8 would be 300 + 75 watts = total of 375 watts - which might make sense for being able to push some higher-end 1080 ti cards hard and is RIDICULOUS for anything less.
 
 I don't think you CAN get a 1070 to hit 225 watts without the GPU melting down, unless PERHAPS you use liquid Nitrogen cooling for it.
 It's hard enough to get my MSI 1080 (the 240 "default" TDP model with the dual power connectors) to get to 220 actual draw as monitored by Nvidia-SMI - and it gets pretty hot when I manage to push it THAT hard.

Exactly. Wish I had the 1070ti SC instead of the FTW2 that I got on Cyber Monday..They sure look sweet though haha. My 6 card rig needs twelve 8-pin connections....Wires what?
 
I jumped on that MONA/VERT run right now. Seem to be getting 44MH/s per card. Think it would be better to just go with Equihash at 500 Sols?

What are you running with your cards QuintLeo?

Currently my NVidia farm is all pointed at ZEC via Flypool, due to the current issues with Nicehash.
If the folks behind Flypool ever opened a ZEN pool though, I'd probably switch.
The other stuff bounces around too much to mess with IMO, and generally the profitability except on SHORT spikes isn't much if any better.
 
 Just don't get me started on Bittrex right now - they apparently decided to change their policies regarding ID 2-3 weeks back WITH NO ADVANCE NOTICE all of a sudden I can't withdraw from them - and their support is getting into Poloniex range "BLOODY SLOW TO RESPOND" levels.
 
 I wish CoinBase would add ZEC to their list of supported coins.
