May I ask for a little advice - I have been mining zec for 6 months now. I have 6GPU's - a mixture of 7970's and 7950's.
Am I still better mining Zcash or should I switch back to Ether? - I remember reading somewhere that ethereum mining uses less power?
any advice appreciated.
thanks
ZEC uses less power, *AND* you will definitely see better return on the 7970 (and probably the 7950) on ZEC.
Also, not sure if your 7950 CAN mine ETH any more - is it 2GB or 3GB?
2 GB cards CAN'T mine ETH as the DAG file is too large.
I don't have a 7970 - but I do have R9 280x which was the same GPU paired with a little faster (by default) ram and has pretty much the same performance on mining.
