so... 580 its worth or better stay with 470 bios modded ? since on gpuz it says drawn 80 watt *gpu only.
With RX470 you will get about 30% slower decred performance. I have RX470 compared to the RX580 it consumes at GPU-Z 85W-90W and hashes with 28.3 MH/S ethereum and 620MH/S decred and the RX580 with the same settings consumes about 95W-100W at GPU-Z and hashes with 28.8 MH/S ethereum and 920MH/S decred so it is better to buy RX580 .
