Exactly. Pay a little extra for a performance boost now or buy an EOL 1080Ti for near its MSRP 2 years ago. What makes more sense? Lol.
Now I'm speaking from a completely new build PoV, with no card residuals considered but …. 2080 is 25% more at current prices. I don't think people who care about price would call that a little.
It needs to be at least half that (12.5%) more powerful without it's new features before most people would call it a decent buy tbh (and probably 20% for me personally). The 1080ti is trending down, 2080 might even go up due to stock issues, assuming £550 is where 1080ti will likely settle at an average low after release, that becomes a 36% price difference. You'll still need a 2080ti to get 4k/60 or 1440/144 running flawlessly. Price wise, 1080ti might end up competing with the 2070 and that will be some achievement if the RTX card wins there based off the spec sheet.
With 9700/9900k right around the corner freeing up that £150/200 will be very attractive.
I love new tech so I *hope* the reviews all prove me wrong.
