Is that a 8800 GTS that I see??? That thing was BEAST back in the day! Awesome that you still have it. I still have a 8800 GT somewhere lol. Welcome to mining, it's an addiction man. I think you'll do ok with the 1060s, you'll definitely want to get more cards once you see the $ come in. I wouldn't focus on CPU or HD mining at all, the payout compared to the power usage just isn't worth it. If you wanted to get a general idea on how much your CPU would earn you daily you could use the built in benchmark that Nicehash offers and test it out for an hour or so. I stick with the GPUs, first I started out with a single 1080, a couple of months later I invested more cards and now have two 1080s and two 1080ti. I'm making decent earnings but also plan to buy 2 more cards.
