Upgrade from 2070S and i7 9700KF to 4070S and 7800X3D worth it?

Hey guys! Some context - im thinking of upgrading my pc with a 2070S and i7 9700, but im wondering if its worth it, I typically play alot of Valorant and sometimes some higher end games but mostly high level Valorant? As im radiant in valorant and i have been experiencing some irritating fps drops - and also not being able to really use anything more than 2K polling rate (or having <200 fps) on my 280hz monitor..

Would u guys think it would be worth the upgrade?

My current specs :
