Would you say the 3080/3090 is enough of a technology evolution to warrant upgrading my Titan Xp on this release? I'm running 4k/60 on most games now, really its the ray tracing voodoo I'm interested in and future-proofing for next ~3 years of AAA game house stuff. Most of the late-late release 2080ti cards and driver releases was coming close to Titan performance, does it make sense then I should compare my current Titan Xp at about the same gap they are showing in the demo release stuff?

The Titan Xp is basically a 1080 Ti with a bad cooler, so draw your conclusions from there.
