I still see a light at the end of the tunnel, 2070 is going to be a much better offering than 1070 was, it's using same 14gbps as 2080, and it's the same 75% of the full 104 die while 2080 is cut. Price difference between the two is $20 more than 1070 to 1080, but seems marginal given 2070 will be much closer to 2080 now.
I too could afford 2080Ti easily,but it's not even about the price,rather about the card itself. I'm not buying such a huge die on 12nm in 2018, better get a placeholder like 2070 with good price/perf ratio that will still be +20-30% over my 1080 (allegedly) and then go big in 2020 when new consoles drop and nvidia is out with 7nm.
If 2070 doesn't deliver that +20-25% though, I'll not buy any RTX card most likely,maybe a 1080Ti but only if price plummets below 2070 level. I'd like a new card though, cause next year I won't get any good money for my gtx 1080 when it's out of warranty.
