GPU Etherium mining concerns

[Latreetim]

i'm wasting 166w per card , 970 for mining ethereum with 22mega

someone has a better performance?

Sure Nano's..

well it cost 60% more, so it's not that better, you pay upfront the electricity for 1 year

I have seen some retailers selling XFX Nano for 399€

That is very cheap, in UK, the cheapest price is £379 including vat.

The R9 nano price has risen quite a lot now. That could be due to the GPU mining of the crypto coins.

could this be that my R9 290 became effective mining . Previously, she gave out 27 mh. and now 28.5

Did you do anything to increase the speed? I am very surprised that the hash rate will increase by itself.
