So fully maxxed out doesnt exist for my card because i have the lowest-end MSI Ventus 3x - the only reason I even got it is because my friend couldn't get it stable at stock in his mini ITX case. The power limit increases to 100% (stock) there is no way, even with a bios flash to increase it higher, so he ended up selling it to me at a discount. That 83FPS is about as high as she will go with full stability.
2.6 Ghz on an 6800xt will spank it all day long.
I'm pretty happy with it though, it has HDMI 2.1, so I can run 120hz Gsync HDR 4K (the 2080ti had to run heavy 4:2:0 compression and no HDR) and is about 15% faster than my heavily OC'd 2080ti at 4k. And it's silent, you know, as a positive side effect of being a turd that can only maintain stability with an undervolt -- still puts out the same scores as a stock 3080 FE so no complaints.
