Two 1060's will have a better hash rate than one 1070 or one RX 580, except when dual mining. TDP on 1060's is good as well <100 W. If you can get two 1060's for the price of one 1070 or one RX 580, then get that.
Im think about DAG for 6Gig. somone says 6Gig is worst is he right?
Thanks
The Dag size is not even an issue for the foreseeable future. The Dag won't even reach 3 GB until early next year and 4GB until 2019.
If Dag size not issue I can Buy 2*480 with my money
but
It says Dag for RX is too bad what you think ?
The issue that chart is reflecting is the future epoch benchmark hash rate drop that the Claymore ETH miner shows affecting the AMD Polaris line (RX 4XX and 5XX) cards. It affects 4GB and 8GB Polaris cards about the same. As of now, there are conflicting reports as to if it's an issue with the Claymore miner or an issue with the hardware architecture of AMD cards. Nvidia GTX 10 series cards are not shown to be affected by the same issue, which is what is reflected in the chart.
