I hope this is considered "on topic".  I've been mining Eth/Etc/Sia for the past few months.  Currently I'm mining Eth/Sia at around 1.5 Eth/day and 6000 Sia/day.  Sia pretty much pays for the power, so the $20 (CAD) per day with my nine GPUs is doing well enough.

Came across info the other day on Xmr for the first time -- the principles of design intrigue me and if it were reasonably profitable it would potentially be something I would mine a little more seriously.  So yesterday for a simple trial I set up the minergate GUI and also the minergate CLI and found that the performance was fairly poor on the mining rigs, and it was hitting the GPU performance of the Claymore dual mining (naturally enough, that was not unexpected.)  So I've been running it CPU-only on a couple or three boxes off and on for the past 24 hours and I've found the hashrate of around 130 h/s to be very low and probably is not even paying for the additional power consumption on the CPUs.

So my question is general: Is there a way to GPU/CPU mine this coin in a way that is profitable, or at least relatively profitable as compared to Eth and Etc?  What kind of hashrate would I need to do about $15-$20 USD per day?  To achieve that kind of hashrate, what kind of hardware would be recommended and what kind of power consumption would a person be looking at?  I know these are general questions, but I'm curious what miners are doing with this coin -- how they are setting up to make it profitable...?

Thank you so much if anyone can answer or point me in the direction of materials that might answer these questions.
