Can't stop thinking about this. I think I'm overtired.
But, yeah, what I took away from the youtube benchmarks is very much in line with my 40% better framerate estimate.
You say you get mostly 55 but dips to 30 and up to 70. Let's just call that 60 and 40% of that is 24FPS. You can see the Farcry YT bench @1440 is potentially 27FPS gain, so 24 is the conservative estimate I said it was. It's true the ultrawide is another million pixels workload from normal 1440p but but it's another 3M pixels to 4k which is an absolute shitload. More than another whole 1080p screen of extra work.(1080p is ~2M pixels) Which brings the importance of CPU back closer towards 1080p, lower res gaming. If real 1440p gets 27 FPS gain then 24 gain for ultra seems reasonable, in Farcry.
If the i5-9400 is as good as a 12 core, as shown in your original benchmark, then you can compare your CPU (the 4690k in the youtube vid) to the higher end ones when trying to work out potential gains from any new 6 core.
So, if you go from 55 fps average to 55 fps minimum that's definitely comparable to a serious weapon upgrade in an RPG. That's pretty much maximised damage rolls. You'd definitely ready for the next tier mobs with a new sword like that!
