I have thinking on to buy AMD Radeon RX570 and combine it with my Nvidia GTX 1060 rig, but now i can't find the most optimal coin to mine with this coin, so i don't know what to buy Nvidia GTX 1060 or AMD Radeon RX570 for mining now :/

can i get help here to what the AMD Radeon RX570 can mine better then Nvidia GTX 1060?
