EVGA GeForce GTX 1070
The EVGA GeForce GTX 1070 isn’t just a great graphics card for gaming, it’s also an excellent mining GPU. This is because it manages a high hash rate of around 30 mh/s without needing too much power. As with many recent EVGA GPUs, the 1070 is on the pricey side, so you will have to take an initial hit when starting up, but if you’re into cryptocurrency mining for the long run, the 1070 is easily one of the best mining GPU currently available.
