Some tips on cryptomining

ROI is return on investment. How much you get back, versus what you put in.

So if a 1080ti was R10,000 then how long to make back your R10,000 + electricity usage. Plus profit. If you spend R20k, it's takes that much longer to get your cash back. That's why the 470/480/570/580 are so popular. They are comparatively cheap compared to the nVidia cards at a similar performance level.
 
And practically unobtainium. Spoke to a guy that runs a local hardware shop, and he said there were three people in today asking for AMD cards, all wanting to use them for mining rigs. He said at least three months before he will have stock available, and already a waiting list.

Conversely. I walked into a computer shop on Saturday looking to buy some thermal paste, lo and behold, on the shelf, sat brand new shiny MSI RX570 and RX 580s - I resisted the temptation...
 
Same answer. Not worth it. My i5-2500K @4.0GHz (admittedly not the bees knees) does about R5/day. That's less than the electricity it's using to do the work. Not worth it.
