Are $/day really the proper metric to be using here? Isn't just the hashrate or BTC/day or BTC/year better?

I think you're right, at least as far and NiceHash is concerned. To compare actual earnings, I think it's better to look at mBTC/day, otherwise the figure is not only affected by fluctuations in the NiceHash pay rate but also fluctuations in the BTC/USD price. To compare cards and algorithms, it's probably better to look at hash rates, although hash rates may not directly relate to earnings.

At any one snapshot, moment in time I think it's the best. At the end of the day we pay for our electricity in $ and purchase our hardware in $ and calculate whether or not this is profitable in $.

But we can't compare that Nicehash was telling me Friday night that I was earning $7.50 per day with my card with your earning $3.50 per day with your card today. Those numbers change based on the $ to BTC exchanges which I believe influences what the users of Nicehash are willing to pay.

If we had an accurate, up to date, table of cards and hash rates we could probably calculate a factor of hash rate to $ for any moment in time. But again, that changes as the exchange rate and value of the digital currencies and what miners are willing to pay to rent your rig on Nicehash.
 
Even though Nicehash payouts fluctuate, it is a safer bet in terms of getting paid, because you are getting paid in Bitcoin, and the risk of mining a new altcoin is left with folks who rent power.

I watched a tutorial on buying hashpower, and it is very much like a stock market. The good news is that there will always be demand and those trying to make money.

I've invested a bit into my rigs, but this is going to be long term. I expect within six months I will have most stuff paid off, it's partly the equipment that costs but also maintenance.
 
I'm drowning myself in information about GPU risers (or PCIe risers or whatever you want to call them). I was anxious to get my other card installed and ordered a set of risers from Amazon. The seller was Amazon Warehouse Deals and they were "refurbished". The upside was the fast delivery by Prime.

One of them is bent and has a crack in the board. I think I'll send them all back. Anyway...

There only seems to be one design / manufacturer of these things. The popular one(s) as far as I can tell right now are the

VER 006
https://smile.amazon.com/gp/product/B01GU94QSQ/ref=oh_aui_detailpage_o00_s00?ie=UTF8&psc=1

VER 006C
https://smile.amazon.com/MintCell-6...UTF8&qid=1498618988&sr=1-3&keywords=gpu+riser

So the VER 006 has a Molex 4 pin power connector and the VER 006C has a PCIe 6 pin power connector. The seller "MintCell" on Amazon explained that there is "Extra voltage regulation components and overcurrent protection on 'C'". I thought to myself "great, I want extra voltage regulation and overcurrent protection, got protect these pricey cards...".

However, apparently you need both 3V and 12V power on the riser board. The VER 006 gets those voltages directly from the PSU on the Molex connector - yellow and red. By contrast the VER 006C only receives 12V from the PSU and has to step it down to 3V, hence the need for voltage regulation components. I don't know if the overcurrent protection is of any benefit as it's probably protecting from overcurrent conditions that it itself creates. Maybe having extra work / components on the VER 006C makes things less reliable, one more point of failure.

There is also a VER 007 out there that has a SATA power connector. When I started writing this post I had dismissed that one because I thought it crazy to use a SATA power connector based on what I saw in other posts about it not being the right connector for the job. There were stories mentioned of melting, even fires because that connector is not rated for the wattage used by the GPUs (that is pulled from the 'motherboard').

Anyhow, looks like there is no one best answer that I can determine. This guy has a rig using all three styles simultaneously:

 
I ordered some of the 006 risers, got them from eBay, as Amazon only have this one https://www.amazon.ca/BLOCKSMITH-Re...&qid=1498629219&sr=8-12&keywords=pci-e+risers which is way overpriced. I'm getting 6 for 135, better than 35 six times over. These ones have molex. Molex is better as the nature of the connector is through hole (typically) which has more mass which is better for voltage. Also, many cheap SATA connectors are held in only by solder, no posts of any kind.

One interesting this is these 006 look like they have pre drilled holes and plates for a PCI-E 6 Pin power connector, it's just not populated. No idea if that would be feasible.

Okay so... after about a week of mining ETH, my two 1070's run on average EDIT (I said 41 before, I was mistaken) ~51MH/s. This is with no optimizations, I haven't really had time to play with overclocking or the like.

I'm actually not using Claymore after having a read in this thread: https://www.reddit.com/r/EtherMining/comments/6h01sc/is_it_worth_switching_from_genoil_ethminer_to/

Regardless of the truth of the claims, I'm not dual mining at the moment so I'd rather stick to genoil just in case. I'm using the latest fork here: https://github.com/ethereum-mining/ethminer/releases

I'm using https://ethermine.org/ as a pool. I also ordered a TREZOR which hasn't come in yet, but will be used as my offline wallet.

Going to try tweaking my cards this week to squeeze a little more out of them. Have some risers and a third card on the way. I'll be getting it up to six when I'm able. I also heard it's more efficient to mine ZCash with nVID and Eth with AMD... anyone know anything about that?

So moving away from Claymore is a good idea. I'm running NiceHash now and it is generating nearly 40% more mBTC per day. The 1080 Ti at stock clocks is displaying Efficiency of 2.881622 H/W in the console, and currently running about 2.073mBTC/Day. This stuff is really interesting. I might invest in another card! Would probably be a good game plan to purchase cards at BTC dips when the used market on them follows suit.
 
So I convinced/showed the boss how much we could make by mining on all our machines. Nicehash currently projects $630 a month if we mine 24x7. Now, I understand that's just an estimate, but if done in force, one could pay off investments very fast!

If you're in a cool/cold climate, don't forget the heating benefits too, which can effectively cancel-out any additional electricity usage. The customer that I'm helping build mining rigs for owns a couple of large retail stores. In addition to the rigs, we stuffed a graphics card into every PC that we could. Now their offices are toasty-warm and they're making money instead of just burning it.
 
I'm currently looking into whether my Dell Wyse ZX0 thin clients would be able to mine as well. They have an AMD APU/GPU which recent releases have started to support. Because they run a 1.5GHZ T-56N APU, they are designed for efficiency, thus electric costs is only aprox. 30 cents per day. If I can at least break even or make a bit of coin, all the merry. I got 11 of these units for $170. I was gonna prep them as low cost PC's for cheap, but if they can mine, i'm getting them going 24x7.
 
Well, that sucked. Estimated money via Nicehash is seven cents a day. Not worth it. I'm doubtful even if I went solo and mined coins directly these could do much.

...and this is the first I've seen of GPU cards being made just for mining (with some not even having video out). By the comments most seem to think it's not worth it.

I've read a few articles about those now but, as I see it, unless they're vastly cheaper/faster than the consumer equivalent, I doubt they'll sell many. With a reduced warranty and potentiality much lower resale value, there's a greater investment risk for very little incentive.
 
So I was looking up my PC build and it has this board, I am not sure what rev but was purchase in Feb of 2013, so can it has 4 slots but the question is if those slots run at 4x how will that impact performance and do they need to be hooked in SLI/Crossfire or as single cards.

Just connect the cards individually. In fact, if you're using risers, you could use all 6 PCIe slots, including the x1 slots (assuming you have sufficient power for 6 cards). Mining only needs a single PCIe lane.

Riser would need a special case to accommodate them and my PSU is a Seasonic 80+ Gold Certified 850W Modular unit also from Feb 2013 as thats how old my main rig is.

Also since each card is independent they don't all need to be the same cards or from the same manufacturer I assume.
