Where am I pointing these cards?
KawPow looks to be the most profitable on whattomine but 10 dollars a day from 100 cards?
Is there anything else that may fetch more profit?
If you want to get the best profit, then choose the most profitable coin. Today it is DYNEX (DNX)
https://hashrate.no/gpus/470Mining this coin is good because video cards do not overheat and in this mode the power consumption is less than when mining coins using the kawpow algorithm.
The best profit is $13 per day, but I don't believe that all your video cards will work perfectly. These video cards have a lot of cooling systems without gas and other problems, so the next 2 months will be very busy for you to set up mining and remove defective GPUs.
The hashrates on hashrate.no are not correct. The 470/570 can reach up to 3300h @ 60w software readed power (depends with the gpu manufacturer).
Biggest problem on this site, the hashrates not up to date for many cards, mostly the older cards, they only work with power consumption over software -> as we all know this is incorrect.
Many dual mining option or single algos are not tested or not well tested.
Whattomine is more "accurate" in terms of power usage, but no dual mine options.
Hashrate.no must work more with the community to get and keep it up to date, but thats not the case.
Specifically in this case, the difference in profit is small, but you are right that the Samsung mother will work better. I sold out of my 470 graphics cards over a year ago because after almost 6 years of mining they were having issues with overclocking and mining stability so I was forced to use a lower overclock.
