What made the Ti's a bad choice was their upfront cost...Which isn't that much in a world where people are paying 450 for a 1070
The upfront cost is not a problem as long as the revenue is better. But GDDR5X is a problem for now.
I agree, the revenue is already paying back the costs. But we now a lot of reasons why ti's aren't (right now) the best options, you can just miner a restrict number of coins and make them profitable, with this variations on market and some bubbles, we could came from guys using gpu and making money to just dudes with gpu only for games. Pls consider this thought...
