Wow... You did a nice break-down, but unfortunately, there are more than 3 variables in the whole story... :) Anyways, I have a similar thinking as ETH mining will (probably... nobody knows the future) not last more than a year, but the profits by mining ETH instead of others are a bit less than double...

But, I do plan to use my equipment for more than just 1 year, so I will probably buy nVidia GPUs as they should mine more other coins... Again, a quantity of coins doesn't mean that they will be better than some X coin who is maybe better supported by AMD... But, probabilities are those that are working for nVidia at the moment...

Thanks for a great comment! Appreciated!
