I can get 1060's and RX 470's for roughly the same price. The 1060 gives give about 290-300 Sol/s with EWBF's miner. and the 480 gives 255 sols with claymores miner. So i will assume the 470 does a bit less. This doesn't make any sense... i've always heard that amd superior when it comes to mining.
I suppose i should go for the 1060? How is it if zcash fails and i want to change to some other currency is nvdia still good?
