I agree with the view that we should not pay more than MSRP for the cards. One way to look at risk is called "value at risk". Taking the worst case scenario, how much money will you lose (example, crypto all crashing 80% tomorrow).
Those who went with 480/580 at $400 USD will find their cards worth $100. Even if their GPU can make $6 a day for 66 day ROI, their value at risk is 75% of their upfront cost.
Those who went with 1080ti at $700, but make $7 a day has a 100 day ROI. However if crypto crashes 80% tomorrow, their cards are worth $600 at least. That's only 14% of their upfront cost, value at risk is way lower.
If a person can put $10K value at risk. He can buy $71K worth of 1080tis, or he can buy $13.3K worth of 580s. For the same amount of money RISKED (not in upfront capital), he gets much much more hash.
After doing some calculation, including rig costs and estimating difficulty of resale, 1080ti are the best. 1070s has to $350 or less for me to consider. 1080tis do suffer a bit more in depreciation however.
