I think you'll find I asked that question several days before the 1070 review you are linking to was posted, but thanks anyway
As it turns out, now we have some data I'm much more interested in the 1070 than the 1080. I reiterate my disappointment in the 1080 - it was touted as 2-3x faster than anything ever when the small print is in VR only. That is down to very poor marketing decisions granted, but it still leaves a tacky 'not as good as advertised' feeling with the 1080. I know it's an excellent card and a real step forward, but it was billed in the build-up as even more.
the '70 though? annihilated my expectations - if the price stays anywhere near the RRP, that is as much of a disruptive force as the original 970 launch was, very impressive, I'm looking forward to a Strix version...
