what is your speed, if it is 22mega per card this is 1 ethereum per two card, so you should get 2.5 ethereum a day
and i'm getting exactly 1 ethereum for two card, with dwarf pool
I'm mining in suprnova, and i get 1.9 eth/day. It is a 70%. What are your settings? Do you run a local copy of geth --rpc? Please provide info
