Apples and oranges.
For one Scorpio has a dedicated hardware to offload CPU utilization....meaning it doesnt need a monster i7 to push GPU utilization.
Reality Check: PC = A bunch of parts slapped together on a motherboard running copper traces.
A SoC engineered PRIMARILY for rendering graphics at the silicon level has unmitigated benefits and efficiencies.
Consoles do more with less, and PC parts age faster because after 1-2 years they are no longer the focus of the driver teams.
Yet we see time and time again that it won't matter for most cases... Yes, scorpio has hardware that will push above it's weight (I didn't say otherwise) but there is hardly anything in it which suggests that it will deliver performance like a 1070.
Not sure what some of other PC comments have to do with anything though. Just sounds like you are taking shots if anything... And I am pretty sure the driver support is much longer than 1-2 years although I am not sure what does that have to do with anything... And it's also not like you need an i7 to take advantage of a 1070 (or most other GPUs) either.
