I finally understand WhatToMine.com.

This bit is which video cards you have. The ones in Red are ATI cards .. the ones in green are NVidia cards. Well, technically that’s just the chipset, but .. yeah. You put in how many of them that you have, and you click the **button**. Green or Red = on, Gray = not on.

If you hover over the button, you get this:

The +150/+500 is the tuning you can do in MSI Afterburner:

You can see the numbers applied .. I’ve also additionally limited power to 50% and temp limit at 60 because I don’t want to burn out my new graphics card…

So you put those numbers in, and then it tells you what it thinks you can do:

This is where you turn on or off the various algorithms .. for example Ethereum uses Ethash and Monero uses CryptoNight. Based on the graphics cards selected, it prepopulates the numbers, but you can change those numbers to reflect what you actually get.

So far its been very accurate – with the tuning in place, i get **29.42** Mh/s for Ethereum, and **680 **h/s for Monero (although Monero I get an additional **+160** via CPU if I so choose).

Then, there’s the list of exchanges. Some exchanges deal in some coins, but not in others, and that narrows down the list of coins .. join Exchanges to Algorithm. My favorite exchange, Binance, is not listed. And then that gives you ..

- The Profit is the estimated Profit per day based on mean difficulty and current prices.
- The % is “as compared to Ethereum”. The time period has to do with market fluctuations over time … looks like CRC is on a roll right now, so its way more profitable (that usually balances out pretty quick as everybody floods to it and then the algorithm stabilizes).

Looking at used graphics card prices … the break even for a card appears to be in the 7 to 10 month range. The lifetime of a graphics card .. who knows? I wouldn’t do it. Plus proof-of-stake will probably flip a lot of things.
