they reckon the gtx 1080 is twice as fast as an gtx 980 and thats without HBM. It will retail for $599 usd ish. Im thinking to try and sell my gtx980ti asus Poseidon for $1000 AUD i paid $1400 6 months ago that should get me a gtx 1080 or i could wait for the gtx 1080 ti .
they are likely talking about stock speeds here, we don't know the overclockability here.
granted you may want to move to the 1080 for the sake of better drivers as the 900 line will be second billing when the 1000's come out, and what if the 1000's can do something well that the 900 cant and nvidia decides to do that to a stupid extent in gameworks (see the 700 compared to 900 in tessellation, and how over the top they made it when 16x and 64x have no discernible difference, yet they decided 64x or nothing and sacrificed old card performance)
