All the nvidia high end card have almost the same ROI
300$ 1060 = 3USD/day
600$ 1070ti = 6USD/day
1000$ 1080ti = 10USD/day

You can check stats by googling Nicehash profitability calculator, nicehash will tell you how much each model are making currently. And the cheapest version of each models are just fone, no need for watercooled or triple fan setups. You can also check AMD gpu on the nicehash profitability, im less familiar with them but they seem similar to nvidias for the ROI.

Can I mix different brands of 1080ti?

Yes, you can mix between all Nvidia cards, even AMD, but that may cause unnecessary bugs,problems, etc.

But many people have a mix of 1080ti, 1080 1070 1060, whatever they can get their hands on. Which is why stock is hard to find and prices are going up.

Each card independently mines for whatever cyrptocurrency they've been tasked with.

So yes, they together do not provide any benefits other than knowing your hashrates between same cards.

Probably too many stolen credit cards used to purchase large amount of cards. The credit card company is probably only covering up to an amount thats just above the value of 2 1080 TI's, so if it reported fraud the merchant doesn't lose out for a loss of a 1080 TI and money.

Also to limit people buying cards to mine and let gamers buy them.

It's probably more of the miner craze, trying to keep stock for people who actually use the video card for gaming, and not someone hoarding all the cards for mining. This has been the case for a while, it cooled off but its picked up ever since cryptocurrency skyrocketed in the past few months.

1080ti's were making $10 in early 2017, then it dipped down to $3-$5 a day for the summer, and since winter started, it jumped back up to $10+. Note that these numbers are at that time, the $10 of BTC in 2018 is like $150 now, the $3 in the summer is $15 now. There is a lot of FOMO (fear of missing out) going on. It's a really unstable time.

dont forget the importance of proper cooling and electrical setup.

i wired 2 20amp circuits to power 2 s9s however i am considering switching them over to 30amp 240volt circuits for cleaner power.

the amount of heat and noise these things produce is something that should also be considered.

The thread pretty much changed from ASIC to general purpose GPUs :)

If I go with 6 1080ti, I can at least build 2 kickass gaming computers.
What can we do with those mining machines afterwards?

You sell the GPUs when it's not profitable anymore

What do you think the value of each card would be when it's not profitable anymore? I remember it happened before but wasn't sure how much each card lost value.

Well, GPUs will still be worth something, because there is still a demand for them, for gamers and such. However, when that happens, there will be a mass exodus of these cards. This whole mining craze is resulting in the overproduction of video cards and RAM, there are warehouses out there with thousands of cards.

It's really hard to estimate what will happen. Video card prices, like all technology, depreciate quickly. But this mining phenomena is creating huge influx of production of these cards, not for its intended purposes. How long will it last? What happens then? No one knows because this has never happened before.


Also, to add, this is definitely good for business, especially nVidia and AMD, and its vendor manufacturers, but how high will this go? Will it reach a point where GPU mining is dead and there are hundreds of thousand of cards that are not in use. What then?

This is why the 1080ti is a popular option, even with its price tag that hasn't moved, instead, above MSRP. It's one of the most expensive, but also has the best return. If mining dies, its still a top end video card that can be used for other things, and should hold more value then the 3gb 1060 for example. There will be hundreds of these cards going on sale on Kijiji, whos going to buy them? Gamers, sure, many of them will definitely upgrade, but outside that, its scary to think what kind of aftermath will result in the industry and the used market, that is if it happens. It is definitely interesting development that will have books written about this in the future.
