I'm running 4 of these cards in a server bought from mad3ga.

Running on Cryptonight at the minute, producing 2440H/s stable across the 4 cards and a total power consumption of 790W, including the servers.

So on Cryptonight algo, that's 610H/s / card and the power consumption is 175W roughly (allocated 90W to the dual xeon server)

All in all, not too bad at the price offered.

Obviously there are greater alternatives out there, but since the price of Vega cards are all over the moon, this proves to be a good option for me.
