7900xtx vs rtx 4080 super

Hello! Im planning to buy GPU for my pc and i cant decide between these two. I use widescreen and my cpu is the 7800x3d unless the 9800x3d comes back to sale if that makes either better.. im very new with computer building.

I would love some opinions! If i understood correctly widescreen is 1440p gaming and atleast on youtube videos rtx7090xtx seemed to pull bit higher fps.

The rtx super is 100euros more in Finland ( so around 1100e). i dont mind paying the extra if its worth it. What do you guys think?

ALSO if someone has better gpu idea around this price range i would love to hear it!
