It's still profitable for me on my AMD rigs - though the profitability has dropped about a quarter over the last couple months.

 Profitability has dropped enough on my GTX 950 and GTX 960 based rigs that I dropped them from their "only intended to do it a short time to help pay for them" Ethereum mining to doing their originally intended purpose. I figure they probably paid for over half the cost of the video cards (I already HAD most of the rest of the hardware involved) over the course of the last couple months for the GTX 960s, and the GTX 950s are pretty much paid for as they were mining longer *AND* cost quite a bit less.

 Those rigs *ARE* still profitable - it's just that the GPUs involved aren't very good for Ethereum, while they CAN do some other "more usefull" stuff while pulling in a fairly close profit level.


 I'm debating seriously about building a few GTX 1070 based rigs - will probably mine with them for a while if I do, then shift to the same stuff I'm doing with the GTX 9xx rigs now, as the 1070 makes a TON more hashrate for not all that much more power. The questions there involve "they make more per watt, but they also COST a lot more per $ income" and I'm starting to push limits hard on both available cash AND available power.....



 GTX 1070 is a MUCH better card for Ethereum mining overall than the GTX 1080 - very similar hashrate, same or lower power efficiency, FAR LESS COST.
 GTX 1080 kicks on gaming and certain other usages, but for Ethereum it's a waste of money.
