cdawall Wattage consumed and ability to stabily provide power to the gpu are directly affected by vrm quality. The most efficient Polaris chip might clock as high on any pcb, but we aren't getting those we are getting 150-200w parts at 1450-1500. The power color under water (which lowers consumption) still can't keep stable with any amount of power pulled.

Yes yes better VRM can deliver more and possibly have better voltage stability (stability i think is more defined by the controller and the amount of caps) im not arguing better VRM isn'timportant. But are you even reading what I said? I can do 1420mhz on mine in crossfire. And i get 1440mhz on firestrike just certain games crash after long gaming sessions so the Powercolor isn't that un-usable like you make it sound like.
