GPU upgrade from R9 390 (2015) for WoW at 30 FPS. Budget: $250

Hello, I currently have an AM3+ motherboard + 650W PSU from 2011 with a AMD FX-8350 CPU and AMD R9 390 graphics card that I upgraded to in 2015.

I mainly just play World of Warcraft and I'm currently running the graphics settings at preset 2 out of 10 at 3840x2160 resolution. It plays mostly fine, but I get ~17 FPS in densely populated towns and raids. I tried dropping the resolution to 1920x1080 but everything just looks incredibly fuzzy, and there's no meaningful change in FPS.

During these drops, my GPU utilization is 100% and my CPU utilization is 40%, which suggests to me that my GPU is bottlenecking.

My goal is to be able to run at 30 FPS in cities and raids at my current resolution and graphics quality, though increasing the graphics quality if I could maintain 30 FPS would be pretty nice. My budget is around $250, though I'm happy to get something cheaper than that if it's overkill.

I'm considering upgrading to an RX 7600 (like https://www.amazon.com/XFX-Speedster-SWFT210-Graphics-RX-76PSWFTFY/dp/B0C59RVD98).

Seems to be no compatibility issues at pcpartpicker.com

This site suggests a >2x improvement in performance for this upgrade: https://gpu.userbenchmark.com/Compare/AMD-RX-7600-vs-AMD-R9-390/m2114669vs3481

Just want to double check: does this sound like a reasonable upgrade? Or is it overkill for my CPU and I should get something cheaper? Thanks!
