Hey guys and people of Steemit,

last summer I had the chance to get some hands on experience building Ethereum mining rigs. Plugging and tinkering I've gleaned a couple morsels of useful information for you guys from that time.

It's easy to get lost in the flood of different graphics card models out there, thus I've compiled a list of models which should work for the task of mining a GPU based coin like Ethereum or Monero. For easier comprehension I've sorted the hardware into the following categories:

Designation, Model and variant, Release, Memory, Power Consumption (in Watt) and Hashrate (in H/s).

I've opted against listing average prices as that is subject to too much fluctuation, but you can just look up what one of the cards goes for at your time of reading. Now then, let's have a look:

I think the metric you should watch out for most is the ratio of Power Consumption to Hashrate. Remember, the hashrate determines how quickly/much you will mine crypto currency at and the power consumption over time dictates how much you are paying for electricity to run this whole shebang. Through this you can compare which GPUs have the most efficient power to mining ratio considering that you need a PSU with enough wattage to run the optimum of 6 graphics cards at a time.

Finally I leave you with a little exercise,

from the diagram below can you learn why "Rig 1" won't work properly even though it has only 5 GPUs out of a maximum of 6?

If there is an interest for further ramblings in technology let me know :)
