My initial motivator to get rid of the 1080ti and replace it by the RTX 2080ti are
1- 2160p performance and weak minfps vs IQ compromises to boost the minFps
2- HDR Gaming induced latency due to SW processing pipeline.
3- Failure too to have a locked 100fps experience on 3440 × 1440p 100hz*
On Average from PCGamer
Avg Fps on 2160pUltra Increase: ((73.7 -55.3)/55.3) × 100% = +33 % in Regular Rasterization
Min Fps on 2160Ultra Increase: ((57.4 - 44.6) / 44.6) ×100 % =+28.7 % in Regular Rasterization
I will enjoy gaming now on 2160pultra and on the PG348Q hitting 100fps - Both Resoutions without IQ compromises
RT + DLSS AA are a bonus features to me and will be gamechanger when both combined.
BF 5 Ultra IQ + Ultra RT is achievable too on 1440p60fps on Rtx 2080ti

Now it is made to make ray tracing possible on a 999 USD card, instead of 68,000USD rendering farms used in Hollywood to create RT scenes due to its heavy computational needs of evey ray traced to be rendered alone. It a revolutionary base to add a new level of realism in the gaming industry.
It' nice to be an early adopter and experiement with it vs entering the game of waiting with already lucklaster performance of previous gen 1080ti on 2160p in regular rasterization.
For any new emerging technology , just give it time with further tweaks , optimizations and combination with other new technology as DLSS to give a final subjective opinion based on the end result gaming experience.
