Dont discount mining algorithms like neoscrypt and x11. profits are way up right now. Im doing a multi-algo mining on zpool.ca
you need ccminer, get the latest from fork of ccminer from tpruvot. Set up a multi-algo script, instructions are on zpool.ca and mine away! Im mining with autoconvert to PEPE and making good profits right now.
You're making 7USD per card per day on x11 and neoscrypt?
"Card" is vague, as its all relative to the processing power per card. I am mining with 750 ti cards. Nvidia is generally slower than AMD for ETH mining in the first place. I am not at $7 a card for the 750 ti. I get about .02 BTC a day for 4 x 750 ti when multi-algo mining with autoconvert straight to BTC. I was under the impression ETH mining was very difficult now and not very profitable.
Each 750 ti does 5.3 MH ETH power. So 4 x 750ti = 21.2 MH which equals about $5.95 a day. I am making $8.40 a day multi-algo mining other alts.
With the P0 state fix, you should get nearly double the hash power on any Nvidia card. Unless maybe it doesnt apply to the 750 ti? But it might be a pain to figure out whats the right command for the right card.
Still, you did your math, so kudo, most people don't.
