Regarding Vega, I have my 6th RACK dedicated to VEGA 10. If there's anything I learned in Mining, it is to decide EARLY and just do it. 20 Rigs now is always worth more than 40 Rigs later. We always end up buying the same cards, ie, RX480 been available since July at tiny discount vs fully ROI. They have beta testing results using untuned drivers and are already showing over 10% faster than 1080s.
