i want to buy some gpu for mining Zcash. . what is best ROI for mining this coin ? AMD rx 480 or 470?
personally i choose XFX RX 470 Black 4gb .. can undervolt a lot and overclock core and memory a lot,along with timings,great card for price.
I have some of these , they are voltage locked man you cant undervolt them outside of bios mod or wattman
