Well I've got my 5900x now. I've not done any proper benchmarks but comparing when the FPS was at certain points in Apex Legends, I was getting 90FPS in the dropship with a 4790k @ 4.4 and a 3080 and with a 5900x @ stock and a 3080 I'm now getting 140FPS.
Not done any more than look at my FPS counter in Apex but I reckon it's approx 50% improvement in frames at 1440p going from 4790k > 5900x in this game.
