Man of Honour
Would people be happy with 1080 performance at 1080 prices out of curiosity?
Not really, for two reasons:
1) Current prices are on the basis of there being no competition and a bazillion miners, so they're much higher than they should be.
2) Being just about able to not quite catch up with nvidia not long before nvidia's next generation is not much competition.
In the general case of like for like in price and performance I'd be looking even more carefully at power consumption/heat generation. If a card requires >350W, I'd need a new PSU as well. The more heat it generates the more cooling I'll need and the more noise I'd have to put up with.
