There is no 1.5 times decrease in consumption there. I watched the tests of cards 1070 devour 180 watts at 460sol well old 280x with the optimization of 185-190watt

You compare not optimized 1070 with optimized 280x. In tests I reached about 210-220W power consumption from GTX1070 on Neoscrypt, but it's not optimal
To get 460sol/s from GTX1070 it could tuned at 140W consumption.
The simple example:
28 nm GTX970 gives 290 sol/s at 140W (OC, DV)
16 nm GTX1070 gives 450 sol/s at the same 140W (OC, DV)

my R9 280 working at 2013? and dont broken, If buy today needs looking the state of the video card, so that there is no smell of textolite, then it is understood that it did not bask more than 85?and coolers state. Profit is achieved faster than expensive cards.But this is a personal opinion

Of course most of old cards are still good for mining, but do not forget about energy effeciency: new cards on 14-16nm techproccess are 1.5 times less power at the same computational power. And if you have limited electricity outlet so now it's time to change old cards to new

So there is no difference there 1.5, but I do not argue at the drain at 1.250Volt they eat up to 250wat it so that the manufacturer does not bother with the fit of each card then at an ASIC more than 70% the card easily holds at 1.081volt frequency 1090/1600

Yes, I do not argue that a couple of years when 1080 will cost 300-400usd it will be the most

mining zec
1080 = +- 500usd = `500sol
1070 = +-400usd maybe more= `400-440sol
Cheesy

buy 7970 aka R9 280x =150usd maybe 130usd = 330sol
500usd 3x card `1Ksol =profit, volts tuning 1.081 =180-190Watts
=====
And show me a game that would not draw the old graphics card 7970(280x)

1080ti = $769-900 = 700-740 sol/s -and that's where my math ends lol

For 900usd I can get 1980sol or 1650sol for 770usd against 740sol, Yes there are risks, but this is another
And when you buy a video card for 150usd it's easy to beat for a month and the more in the system of cards, the less time you need
But this is my personal opinion

Yes, and about the breakdown of the video card, if there are two cards 1080 to 770usd and one suddenly breaks, then 50% of the speed is lost (sol), and if for example the money in the system is 6-8 cards and 1 breaks then the loss is only 1/6 or 1/8 speeds (330sols) Something like this

And buing new GPU you get a 3 year warranity, but buing used 7970 or 280x it can be broken in few days and you will get nothing

Currently definitely 2 gtx 1070s, they get more hashrate in ZEC, Eth and probably every other algorithm, looks like vega isn't very good.

Just buy used rx470 8GB , you can get more return on that.

Don't know how to close the thread.

I just cancelled the order for AMD Vega 64

Found a 1080ti at a cheaper price point.

It may be slower but it'll have a better resale.

Thanks

How much did you got your 1080ti for?

I had same question few days ago.
Vega was not available and it seems for now vega can be bought for lolz!
1070 was only like 15 eur cheaper than 1080. I found those zotac mini 1080 with gddr5x quite interesting and cheap - 415 eur +vat seemed for me like a good deal when 1070 costs only few eur cheaper. And it has one 8 pin connector. Well, 1070 ir very nice card, but in this case I have decided to play with 1080 a bit.

If you are planning to put cards in pc case then go with two 1080ti. I have tried to put 4 evga 1080ti sc2 on asus apex motherboard but it is basically impossible to cool them. So I am using just 2 right now.

In theory if you can find motherboard where there is 2 slots between each 16x pcie slot then you can use 3 cards in big case like Define XL R2 (which has 11 pcie expansion slots) but I have not found such motherboard as triple sli and cf is long dead.

Also, in theory maybe it is possible to cool 4 wattercooled cards on such motherboard like asus apex - you need reeeaaalyyyy big case then and place to fit 4 watter coolers. But Then it would be one baddaasss video rendering rig (because gaming is using only 2 of them) and mining rig in spare time

You made the right choice. AMD Vega 64/56 hash rates are out. At 32-36mh, they dont even come close to the 1080ti because of power consumption. The vega's power consumption will eat up your profits.

Buy 1 1070 and wait a little to see if Vega will worth

lol issue is my machine has only 3 slots- I have one 1080ti

I thought another AMD would be nice- however, AMD 64 Vega I jumped the gun and pre-ordered - so if I don't decide quickly I'd have it on my hands.

Hello,

I'm very confused-

Should I buy Vega 64 (faster memory and more Raw computing power)

or 1080ti - overall a better card and much lower power consumption and way better at games.

or dual 1070- (lowest power consumption)

They all will cost the same.
