just got the third 1080 water cooled gpu
this board is running
3x 1080 ti's
1x ryzen 1800x
https://www.nicehash.com/miner/146UJM5kgzLVUV23CXCf33KQKHckoX1gx3lenden and the 7500t are two other cpus running xmr
both most of the earnings are from the x370 board.
while I am easy over energy
i.e. 600 watts is 15 kwatts a day or 3 usd a day at my summer rates of 20 cents I earn about 8 so 8-3 = 5 bucks a day so the time has come to stop buying gear.
in 1 month my power bill will drop in ½ so 8-1.50 = 6.50 a day which means very tight margins for now.
I remember when i started with this mining thing, early this may, i was having those same numbers ($6-7 a day) and it was just with two gtx 1070 only.

by the way, how come does your electric bill get dropped by a half after summer? Here in mexico it works the other way around, summer rates comes with a big discount so you can turn on your ac without hurting your pocket.. i guess you dont have this infernal south baja summer
