Hello, I was wondering how many hashes per second, the AMD Radeon R7 240 4GB, Nvidia GeForce GT730 4 GB and NVIDIA GEFORCE GTX1060 produces on the following coins:
Ethereum
Zcash
Monero
Your first 2 GPU options are garbage and not even worth trying.
If you got the larger memory 1060 6GB you can try mining ETH with that one. You can also mine XMR with it.
It uses very little power and you will make a little everyday. However if you want more money than try to get at least an GTX 1070 or 1080Ti.
