GPU upgrade advice

First time poster, trying to follow the rules. Let me know if I should be asking elsewhere, or point me to resources where I can do more research.

I'm looking to upgrade the GPU on my 4yo gaming PC (my first and only build) for say \~$200 to continue to play single-player games on Steam/Windows 10. (e.g. Hellblade Senua's Sacrifice, Outer Worlds)

Here are my existing parts: [PCPartPicker Part List](https://pcpartpicker.com/list/FWMsn7)

Can I upgrade to: [https://pcpartpicker.com/product/cqfhP6/xfx-radeon-rx-590-8-gb-fatboy-oc-video-card-rx-590p8dfd6](https://pcpartpicker.com/product/cqfhP6/xfx-radeon-rx-590-8-gb-fatboy-oc-video-card-rx-590p8dfd6) ?

Will I see much performance improvement in newer games? Am I crazy to even try upgrading it? It looks to me like the length increase won't be an issue.

Thanks.
