Cool, I love seeing data tables. Thanks for putting in the effort.

Semantic criticism: This data is about revenue, not profitability. Profitability data would account for initial costs as well as operating costs and then could be used to generate the ROI data and payback period, which is what you're after if you're hunting for the most profitable outliers.

Even if you're using someone else's hardware and not even paying for electricity, those costs do exist (for someone) and would exist for anyone looking to set up their own mining rig.

This data is nice and maybe there are some nuggets of useful information, but it seems to boil down to this: "more gflops = more grc", which isn't exactly illuminating.

I think you can take this a lot further. Maybe start by adding the wattage per card. Then you could have a function like "GFlops Per Watt", which might be helpful in itself. Add in the market price of each card, add in the rest of the rig costs (case/psu/mboard/ram/etc...), and a few columns for low/mid/high energy cost scenarios. At that point we can compare payback periods and actually be able to recommend things based on a new user's particular situation (money available to spend, their own power cost, etc...).

This is a good start though as a guide for existing hardware and users asking "How much can I make with hardware X".
