If AMD can't beat the 1080 with Vega this year, then it's doom and gloom. If the 1080ti goes without compeition too, then it's also doom and gloom. If one year after Nvidia isn't enough to catch up... doom and gloom all round.
We need competition. Both so we can have another product to buy and also to try and keep these ridiculous prices under control.
I don't know about the doom and gloom tbh .... If you look at market segment I think the money is not in the top tier ... I believe If they can make something that is 1080 perf for less money they have a winner.
Consumer is already the winner when you look how nvidia priced the 1080ti
