Reddit chatter saying that it will be roughly the same as building a rig, so 180MH/s for about $2500. That's what the performance of this asic will be.
Humans suck at predicting the future, so either way you merely have to decide are you going to tear your rigs apart and have nothing for awhile, or forge on until something better emerges and then pivot? I had ZERO trouble selling an old GTX 970 I didn't want for pretty good cash. All the cards I have now are hot items. Someone will buy them IF I need to sell them. I don't think I will but I'll wait for the facts. I've got birds in the hand right now.
