No idea why people are still mining ZEC with their 470/480. Basically throwing $0.15-$0.20 daily per card away in profits.
on top of that i can run more ZEC rigs than eth rigs the power savings is that good so it evens out in the end
What? There is no evening out of anything. If you have 470 or 480 cards, you are making more PROFIT (factoring in power consumption) by switching to ETH.
