thanks all for the reply guys. really appreciated your advise now i'm using 5x 1070 and 1x 1080ti just basically added 4x 1070 lol. anyway i do have new concerns can mine using window 7? and what best application I can use for these cards?

I hate to be harsh but why even bother to ask for advice on this forum if you are going to ignore it? Obviously you have it set in your mind what you want to do already, just go for it.

Plenty of posters have already suggested not buying more cards as the $20-$30 per day per rig times are over. Right now (this moment) with your setup (5x 1070 and 1x 1080ti) and assuming 8 cent kWh power you can earn maybe $10 a day with your entire rig while mining Zcash. A few months ago that was probably $40 a day. A few months from now it will probably be $5 a day, a few months later it might be $2 a day.

I do not know what you paid for your system, but looking online a cheap 1070 is around $400 and a cheap 1080Ti around $700. So just considering the investment in cards alone you have around $2,700 locked up in hardware. It may even be closer to $3,000 if we add in the other components, but since you haven't indicated if you already had the rest of the system I will let it go for sake of argument.

So if everything stays rosy and we do not drop below $10/day in profit you are looking at 270 days to get your money back, or ROI/breakeven. However, if we consider in 3 months time we seen a decline from $40/day to now $10/day in profitability, it is not unreasonable to think that it is possible daily profits could continue to go down even more in the future. So maybe in another 3 months you are looking at $3/day in profits and that 270 days turns into 365+ days. Basically you are forever chasing a ROI that may never happen.

Even if the price of a coin goes up, you may find a temporary relief from the loss of profits, but as profit goes up so does the number of miners who are adding more hash power to capture a little piece of that pie. So over the longer term, even with increasing coin prices, since hash power is also increasing your profit will continue to erode.

However, I don't expect you to read or even consider any of this. I would not be surprised to see in another week you proudly inform us that you now own 2 rigs of such a setup. Well I can only wish you good luck in your endeavors.

Yeah....lol.....

It gets worse also. If Nvidia stays on the usual course, they will be releasing the new series this spring which will cut the value of the new 10 series cards in half. So, while the resale value of a 1080ti (and 1070s) are high right now, they will be down quite a bit. When the 10 series came out I bought a brand new 980ti for 300.00 from Microcenter. If profits keep moving down and the market flood, cards will be down even more.

Some people need to learn the hard way.
