The last days are getting less buying amd mining hardware. Because of the new very high price, and because of its unavailability. Nvidia is currently far better and more favorable, and if this goes on, AMD will return to red...
Nvidia prices have blown up too though... both are totally not worth it where I live (Netherlands). €300 - €450 range for a 570, €400 for a 580, €300 for a 1060, €550 - 650,- for a 1070, 600-900 for a 1080
So yeah......
