5080 vs 7900xtx

I'm building my first PC around a budget of 2500$ in a Zonsbo Z20, all white. I just got lucky and preordered an MSI RTX 5080 16G VENTUS 3X OC WHITE for $1339. I've been looking at some RX7900 XTX models and think I can snipe one for maybe $999 - $1100. However, if I want a white one it would probably be a little more. I really don't know if I'm going to sink another 1000$ in a 4k oled monitor and will probably stick with a 1440p oled. It's a bit overkill for the games I mostly play which are usually FPS/Multiplayer but I want to play GTA 6 when it releases etc. Should I just stick with the 5080? I'm sort of leaning towards it because even though its not that great of a value, I can't find a 4080 super for anything under 2k and there's not really any upgrading to be done since I've been playing on a gaming laptop.
