Best Graphics Card for Ethereum MiningIf you are thinking of getting into Ethereum mining and start building your own Ethereum Mining Rig so this article helps you a lot for choosing best graphics card for mining ethereum. The main part of the GPU Mining is the graphics processing unit (GPU). The better you have graphics card, the more you get profits from Ethereum Mining.
First of all make sure what do you really want to optimize for?
Lowest upfront cost per unit hash rate?
Lowest ongoing cost (upfront + electricity)?
Best hash rate per unit electricity? Lowest heat (and electricity) per unit hash rate?
In my opinion, the best current GPUs are the following below for Ethereum mining but the answer is more complicated And all this depends on the cost of hardware and the cost of your electricity.
For the lowest heat and electricity per unit hash rate I would suggest R9 Nano.
Hash Rate: 28.5 mh/s | Cost: 497$ | You can get from here
For best hash rate per unit electricity I would suggest the R9 Fury X.
Hash Rate: 33 mh/s | Cost: 330$ | You can get from here
For the lowest upfront cost, possibly the R9 290
Hash Rate: 30 mh/s | Cost: 350$ | You can get from here
For the Hash Rate and electricity + cheap cost RX 390x
Hash Rate: 27.5 mh/s | Cost: 440$ | You can get from here
For the highest hash rate per GPU, the answer is the AMD HD 7990
Hast Rate: 44 mh/s | Cost: 588$ | You can get from here
The HD 7990 harder to purchase from stores as this series has been superseded by the R9 series released in 2015. Internally, the HD 7990 with 6Gb RAM consists of two AMD HD 7970 GPUs with 3Gb RAM each packaged together.
Here is a link to a site that allows you to compare the different GPUs - http://www.mininghwcomparison.com/list/index.php?brand=both . Type "Ethereum" in the filter.
You don't need a fast motherboard and CPU but make sure you know about this, AMD CPUs use more electricity than the equivalent Intel CPUs but AMD CPUs are cheaper than Intel CPUs.
Finally Now it's up to you which graphics card and hardware's you select for Mining Ethereum.
