I recently upgraded my setup from a Z390F board with an Intel i5-9600k to a B550-A ROG STRIX with an AMD Ryzen 5800XT, and I also added a 3080ti to the mix. Surprisingly, my frame rates in games are either the same or even lower than before. For instance, I'm getting around 200-300fps in CS2 now, whereas I used to see 250-350fps. In Minecraft with shaders, my frame rates dropped from 60-90fps to just 35-45fps. I've installed the AMD chipset drivers, ensured my Nvidia drivers are up to date, and haven't changed any graphical settings. I'm frustrated because I expected better performance from this upgrade but it feels like a downgrade instead. Should I consider reverting back to my old system? I'm completely confused about what's going wrong here.

Also, verify if XMP/DOCP is enabled and check that your RAM is running at least at 3200MHz. Make sure the 5800XT isn’t thermal throttling either—those GPUs can hit temp limits easily if not cooled properly. And double-check your game installs since it sounds like you kept your drives from the previous setup.
Did you enable ReBAR in the BIOS? Also, make sure your RAM speed is set correctly. It can make a big difference! Sometimes, just resetting the BIOS and tweaking those settings can help improve performance. I usually go in and turn on all the chipset features myself to optimize everything after a major upgrade.
If you switched from Intel to AMD, you might want to consider a fresh Windows install. It’s important especially since you may have leftover Intel drivers that could interfere with performance. Even if you try to uninstall them manually, some files can linger and cause issues.
Check your temperatures under load; throttling could be an issue. And as others have mentioned, a fresh install of Windows is usually a good idea after switching platforms to avoid compatibility problems with old drivers.
A general rule when adding new hardware: always reset the BIOS. That’s been my go-to since my first build back in the early 90s!
Did you perform a fresh Windows install? That’s recommended for a major switch like this, it can really help with performance hiccups. Just saying, cleanup helps a lot.
Exactly! I always do a BIOS reset myself. It’s a good practice to ensure everything is detected properly and running optimally.
