£1500+ for a power hungry graphics card just continues to place tech as bad guys in this age of responsibility, as did BTC proof of work.
When you consider the computational power afforded assembling a system at equal monetary value, whilst it's clear said machine to run such a card is not a simple side show, it's a disproportionate amount of expenditure on one item.
Intel I'm not so sure (vis a vis power requirements for latest processors versus the competition) share the "correct" world view but it's difficult to see how they could otherwise achieve any market inroads; except in the 'forgotten' market segment (which is where I'm sure the majority of users would prefer to exist).
But yeah, (low) power to them. Plus a third way is always a nice 'to have'.
