So, when it comes to Ethash, the Acorn will increase Nvidia's UP TO 10%, and AMD's UP TO 15%. And you need minimum 1 acorn per 4 GPU's, so best case scenario is you're getting about $0.45 per day boost. the Cle-101 is $200, so it'll take over 400 days for ROI.
Am I missing something?
I know it may save some energy, but most people run at 75% TDP anyway.
