4K Performance?

Curious to see what kind of performance my fellow 4K enjoyers are getting as I’m looking to upgrade my GPU. Would love a 5090, but not for $4000, so I’m considering a 5080.

Currently at 4K and on high graphics settings (epic is too much) I’m getting around 60-70 FPS on a 10GB 3080. FPS drops 10-20 frames when aiming down optics or under NODs.

Also running 64GB of DDR4 RAM and an i710700k. Thanks!
