Upgrade on AM4 or build new on AM5?

Edit: thanks everyone for feedback. Think I will stay AM4 and try and get a 5080 or 4070 TI Super.

Hey everyone, my current build is from 2020 and im looking at upgrading.

I game on a 3440x1440 LG 34GN850-B with a Ryzen 5 3600 and 2070 Super. Play mostly AAA or first person games on the PC. I havent been unhappy with the build by any means but its starting to not get the performance id prefer in newer games at native resolution.

Currently pricing out upgrades and am debating upgrading CPU to a 5700x3D and the GPU to a 4070 TI SUPER or better.

Is this going to get me several years of great 3440x1440 gaming or should i go ahead and build a new pc.

Current Build:
RYZEN 5 3600
MSI B450 Tomahawk Max
EVGA 2070 Super
2x8GB RAM

Considering spending around 1500 to upgrade this build to a 5700x3D and at least a 4070 TI SUPER some more ram and a new cooler or around 2500 (minus whatever i can sell this computer for) on a new AM5 build with hopefully a 5080 and something like 9800x3D

Price isnt the first factor but if sort of maxing out my current AM4 based build can get me several years of high quality gaming then i dont need to throw money away chasing a new build (though it would be fun to build a new one). Going to try for the 5080 and if i can get one will probably build new to try and get the most out of it.

What would you all do? Cheers.
