If you're already spending 900 bucks on a card, I dont think 1100 is going to really be something you gotta think about it. It was spending 2k on a video card that got my attention, 1100 wouldnt. I see your point though that the difference is not that noticeable.
The thing about the 3090 TI that makes me feel weird is that it seems to have the tools to do everything you could possible throw at it, but the tech still isnt powerful enough to have a game maxxed out and still get a comfortable (to me, anyways) frame rate. A game can look stunningly gorgeous at 35 FPS, but in the end, Im just going to tweak the levers until Im back up to around 120 FPS. Usually its shit like Ray Tracing and if I turn that off, the performance shoots up so much that I might as well have a 3080 TI.
I think the 4090ti is probably going to run all those same features at probably double the FPS and... although not ideal, would be worth it.
