My Question:

One RX Vega 56 / 64

OR

Two XFX Radeon RX 580 GTS XXX Edition 8GB GDDR5

What u guys mean? Which of both have better performance?

There are a lot of factors to consider when choosing the right GPU for you. Do you already have a built out rig? What is your PSU max consumption? Are electricity costs expensive at your location? Do you plan to expand and buy more GPUs in the near future? Building a profitable mining rig needs to be planned out to very specific details.

If you are looking to get the most efficient GPU in terms of hash rate / power consumption then i suggest getting the VEGA. Mine hashes 1900h/s cryptonight at only 130watts.

Thank you for your answer. Basically I do not want to mine ETH but rather cryptonight and some ethhash coins. At the moment I use only 2 strong PC systems but a rig is planned later with several GPUs. The power costs are not low for me, but I underclocke my GPUs in principle, my current RX 580 consumed, for example, currently under load only 70 watts.
