my R9 280 working at 2013? and dont broken, If buy today needs looking the state of the video card, so that there is no smell of textolite, then it is understood that it did not bask more than 85?and coolers state. Profit is achieved faster than expensive cards.But this is a personal opinion

Of course most of old cards are still good for mining, but do not forget about energy effeciency: new cards on 14-16nm techproccess are 1.5 times less power at the same computational power. And if you have limited electricity outlet so now it's time to change old cards to new

There is no 1.5 times decrease in consumption there. I watched the tests of cards 1070 devour 180 watts at 460sol well old 280x with the optimization of 185-190watt
So there is no difference there 1.5, but I do not argue at the drain at 1.250Volt they eat up to 250wat it so that the manufacturer does not bother with the fit of each card then at an ASIC more than 70% the card easily holds at 1.081volt frequency 1090/1600

Yes, I do not argue that a couple of years when 1080 will cost 300-400usd it will be the most
