Contemplating Processor for my 1440p Terra build

Hello! Looking for some opinions on processors. I'm building my first new PC in 12 years. My primary goals are 1440p gaming performance and longevity - my last PC lasted me 12 years with minimal upgrades. In regards to gaming, I definitely don't need everything completely maxed out.

I have a 9800x3d for MSRP on order scheduled to come January 12th. After doing some reading, I came to the conclusion that processor might be a bit overkill for my needs and found what I thought was a really good deal on a Ryzen 5 7600x for $194. That processor will be here by Friday, which is exciting as I will be able to build a month sooner. I'm starting to think the 7600x is probably not going to have the longevity of the 9800x3d - and maybe i'm making a bad choice for the long haul. Anyone have any advice for me?

Here is the rest of my build. Keep in mind that if i was sticking to the 9800x3d i would switch the the Noctua NH-U12S cooler.
