These are all the cards I had access to and the currencies I tested on Minergate. Faster newer CPU's will affect the speed very slightly. CPU's can mine but unless you have a very fast one it will take a year to make $10. :)

All the cards have a 100 MHz overclock on memory only. There wasn't enough gain going above 100 MHz to be worth
killing the video cards. (you will see a slight gain at +50MHZ on the clock and 125 to 150MHZ on memory) I ran each coin for 10 minutes to see an average speed. Of course the speeds
are always changing up and down. So I went with the lowest average speed.

First thing I learned was buying 1080's or 1080 TI's is just a huge waste of money. Unless you really just don't have the space. The best hash for the cash are the EVGA 1060's you get about 20 MH/s on Ethereum, 1080 SC 23, 1080 TI 28 to 30. So for $340 you get 20 to 21 (using the GUI) for $700 to $1,000 you get 23, for $1,100 to $1,400 you get 28!

Three EVGA GTX 1060's get 60 to 63 MH/s for $1,020 (You will make about $50.00 per month depending on coin values.) Coins go up and you have a six card rig. You will make just over $100 per month.
Just enter the hash rate to see monthly income. https://www.cryptocompare.com/mining/calculator/eth
(It's not rocket science just use one of the crypto calculators.)
One 1080 SC2 you get 23 MH/s for $800 to $1,000.
One 1080 TI you get 28 MH/s for $1,300. (the worst hash to cash card)

The best hash per cash on XMR Moreno are the RX 560's they are way to slow for anything else. But on XMR you can average around 360 H/s for $139 to $169 per card. Plus you can run 12 of these cards on one 1000 watt power supply! And 12 cards would get 4320 H/s! Using the Claymore Console Miner but you need a board that can do 12 cards.


You will notice that the 2 gig Nvidia cards do really well but remember at only 2 gigs there are coins they can not mine.
But if you're on a budget 12 EVGA 2 gig 1050's can hit 3840 H/s on XMR and they are only or were around $112!

Yes you can mix cards as long as they are the same type of GPU. ATI-AMD with ATI-AMD and Nvidia with Nvidia.
