In this article I will try to find out what card is the most efficient by the main mining ratio - Power/Price/Wattage.

I will review only the new actual graphic cards, that you can buy now and have a full warranty.

The prices I will take from the "Newegg.com" shop by default.

So, here is the list of the cards, I will compare (I tryed to find the most cheap model, but good):

AMD Radeon R9 390 8GB - 275$

NVIDIA GeForce GTX 1070 8GB - 440$

AMD Radeon R9 Fury X - 380$

That's all the cards for now.

As you can see, there are all non-reference cards, exept R9 Fury X. Why? Because the new cards (RX 470 and RX 480) have a terrible ref. cooling and also have some problems with PCI-E power consuming, R9 390 is too hot and needs a powerful custom cooling too, GTX 1070 have a good ref. cooling and no any problems, but the custom (for ex. MSI Gaming X) model have a lower price, better cooling and functionality vs ref.

That's why I have chosen these cards. We need to buy not the cheapest model, but the model, that will have a good overclocking capability, potentionaly the long life and good cooling without extra loudness.

I think, these cards fit these criteria.

The most profitable algorithms for the cards.

AMD cards have the best profit while mining ETH+SC/ ETH+DCR/ETH

NVIDIA cards are good at mining LBRY/ MonaCoin, VertCoin/ SiaCoin/ XCN/ ETH+SC/ ETH

I will focus on ETH+SC and ETH only for AMD cards.

And LBRY and ETH+SC for Nvidia card.

The conclusion.

Surprisly for me the best card for mining is Radeon RX 470 4GB (Sapphire Nitro+). But anyway I advice you to buy not it, but 8GB model, it will have more perspectives with its fast memory.

R9 390 is still a good choice, especially with discounts, if you have not expesive electricity.

Nvidia GTX 1070 is a very good card with amazing power efficiency - it consumes the same average 150W as RX 470-480, but it is a lot more powerful. The bad thing is the price, it costs 57% more than RX 480. The good thing is that you can set up more hashing power with less power consumption on every rig. And also keep in mind, this Nvidia card have very good hashrates on other algorythms (x2-x3 more than RX 480).

And don't forget, there are a lot of hints, mods, modded bioses for the cards, so you can expect higher hashrates or lower power consumption.

Ok. I've chosen the best video card for mining for today. It is AMD Radeon RX 470 8GB!

Let's build the test rig with it!

We'll need:

GPU AMD Radeon RX 470 8GB (Sapphire Nitro+) - 5x =1200$
MB Asrock B150 Fatality Gaming K4=95$
CPU Intel Celeron G3900=48$
Memory GSkill 8GB DDR4 2400=32$
PSU EVGA SuperNova 750W - 2x=140$
Hard Drive HGST 500GB=40$

Total rig cost: 1555$ (wow, beauty number)

Total power consumption of the rig will be around 900-1000W. So we have 500W in reserve.

What about profit? We'll earn with this rig about 0.6255BTC or 375.3$ Monthly by mining ETH+SC (minus eletricity 375.3-72=303.3$).

And after 5 months (5.13) we'll return our attachments and have a clear profit.

For the compare I will take a look on the rig with GTX 1070 for the same price.

For the same price, even a bit more, we can buy only 3 GTX 1070 for our rig. It will look like that:

GPU NVIDIA GTX 1070 8GB (Gaming X)- 3x =1320$
MB Asrock B150 Fatality Gaming K4=95$
CPU Intel Celeron G3900=48$
Memory GSkill 8GB DDR4 2400=32$
PSU EVGA SuperNova 750W =70$
Hard Drive HGST 500GB=40$

Total rig (GTX 1070) cost: 1605$.

Total power consumption - 650W.

The profit: 0.5544BTC or 332.64$ - 36.72$ (electricity)=295.92$ monthly profit.

So, the rig with RX 470 8GB is more profitable with the less cost. But the rig with GTX 1070 have the opportunity for adding 2 cards yet. It's nice, that NVIDIA can mine very well too.

That's the end of my review. I hope you like it.
