Are you saying that the best way to get ***really*** high nps rates is with hardware [maybe such as used by Hydra?] as opposed to using a PC? Incidentally, I am really feeling ignorant right now. How did Hydra get such high nps? I hope you don't mind helping a beginner along on this confusing stuff.
