god people and their power cry's. It's a 180W card. It's more efficient compared to the 580. The 2100Mhz memory is a 'nice bump' but that was possible too with a 580. The real difference is the allowance of higher clocks over 1550Mhz or so. This, only a handfull, or liquid cooled 580's can do. It's not bad, but compared to the 1080 it's extremely inefficient yes. But the 1080 comes with a bigger price as well.
The 580/590 is a good midrange card which does everything on 1080p at ultra settings in most games. Overclocking on these cards is pretty fun. And know that the TDP is the absolute maximum the card can do; not what it uses. Apply AMD Chill, a FPS limiter equal to the refreshrate of your monitor, and then the card spits out perfect frames with less then half of the boards TDP.
