I also wanted to ask when using this program with GTX 1070 cards, are there specific drivers I should use, or just the most up to date ones?
With Nvidia use just the latest drivers.
I just got my first gtx 1070 delivered today for my build and want to test it out in my everyday PC. I was wondering if I have to overclock the card or does this miner control software already scale the clocks because there is a 1070 folder?
No overclocking is performed by application itself. It depends on miner, that you are using. If it has special parameters for overclocking, they can be added to cofig. Miners for Nvidia usually don't have such features. So the best way to do that is via apllications like Afterburner.
