Right now I just realy wanna know more about those "flashing bios" things they're talking about, overclocking my GPU and how/where I can get the most profit out of my card.

edit: Tried r/ethermining and everyone there are saying I'm too late and nobody is making ROI? are they too negative or are they right?
I also calculated my electricity cost and in dollars is something like 0,15/kvwh, is that too much?
