My best 1080Ti card does 754 Sol/S @ 3.72 Sol/W while consuming 208 Watts (Max power on that card is 330 Watts - MSI Sea Hawk EK)
If this new volta is twice as efficient at the same power level, is it conceivable that it would be able to do about 1,500 Sol/S @ 7.44 Sol/W?
If so, I'd gladly pay $1,500 for such a card, but not $3,000.

That's weird. The math says that should be 3.625, not 3.72.
Regardless, 208w saved per hour would come out to $19/mo in electric savings. That'd take 7 years to bridge the price difference between what you're willing to pay vs what it costs.
We might as well wait until March/April when the consumer level volta cards are released.
