I want to build 1070 rig, I have few choices:
Palit GeForce GTX 1070 Dual 8GB - 480e
Palit GeForce GTX 1070 Jetstream 8GB - 530e
Gainward GeForce GTX 1070 8GB - 480e
Gainward GeForce GTX 1070 8GB Phoenix - 530e
What do you think? Is the 480e cards good enough for ETH/Zcash mining, and is there big difference between these 4 cards? Can I dual mine with these cards?
