You can go for a 4th gen Ryzen (5600X etc.) but you'll need to update the BIOS to P4.60 Version.
Maybe a better air cooler or AIO.You need to make sure that your case supports the product you choose.
You can upgrade the GPU for a RTX 3000 or AMD Equivalent.In this scenario you need to make sure that you have a decent quality PSU.
Maybe you can move your Windows 10 into a gen3 NVME instead of a 2.5'' ssd or HDD, if you don't already.
Maybe more RAM.
Your post's info isn't enough for some clear instructions.
