for amd u can mine etc or expanse or use nicehash to select the most profitable coin automatically
btw how much you pay per 1kw ?
I like this option, using the Nicehash to compute the most profitable coins for your graphics.
When you will start the nice hash software you will see the benchmarking option, it is anyway mandatory to run before you can even start the mining. The benchmarking process will take few minutes and will pop up window telling you which graphics card you have connected and which coin can be mined with it for best results. The benchmark process consists of 6 steps, it will internally checks the hash rate for different coins, run the algorithm on it and will compute the power finally.
With almost all the AMD VEGA you can mine Zcash with good profits. Hope this helps you. Go through the nice hash soft quickly.
