I recently upgraded my PC with an AMD4 motherboard, 32GB of DDR4 RAM, and a Ryzen 9 5900X CPU. I moved from an RTX 3080 to an RTX 5080, but I've been noticing some performance issues. My GPU usage is hovering around 83-92%, while my CPU runs between 40-55% when playing games like Red Dead Redemption 2, Spiderman, and Cyberpunk. In contrast, with the RTX 3080, the GPU was maxing out at 97-98% utilization and the CPU was only at 20-25%. My FPS has been inconsistent at 4K resolution, showing the same frame rates in Marathon and Spiderman as I did with the 3080, and the same goes for Cyberpunk and Black Ops 6. The only improvement I see is that the RTX 5080 is significantly quieter and less demanding in terms of power consumption. Did I upgrade too much, or would the RTX 4080 Super have been a better choice?

Your CPU really could be the issue, especially if it's only using 25% of its power while gaming. Games are usually optimized for only a few threads on CPU, so it's not uncommon to see lower usage on a multi-core chip. I'd suggest you try tweaking the graphics settings to put more strain on the GPU. Also, check your power supply to make sure it’s adequate for the 5080.
It sounds like you might be hitting a CPU bottleneck. The Ryzen 9 5900X is still a solid chip, but a jump to the 5080 is pretty significant. If your GPU usage is down and FPS stays consistent, that's usually a sign that your CPU is limiting performance. Just to be safe, check that your drivers are updated and Resizable BAR is enabled before returning it. If you plan on upgrading your CPU down the line, keeping the 5080 makes sense. Otherwise, if you're sticking with the AM4 platform, it may be a bit overkill for now.
Exactly! I switched from a 3060 Ti to a 5070 and felt the same limits initially. Most games I play run fine, but for anything super demanding, my CPU struggles. If I were you, I’d probably stick with the 5900X for now.
It seems like a driver issue could also be playing a role here. If DLSS isn't helping, definitely do a clean installation of your GPU drivers. But remember, the 5900X is still a strong CPU, so it shouldn't be bottlenecking too much. What wattage is your PSU? Sometimes, that might cause awkward performance as well.
I've got an 850 watt Gold PSU running smoothly, so I think that part's solid. Mulling over a potential CPU upgrade though if this continues.
I was in a similar boat with an RTX 3080 and saw inconsistent performance when I upgraded my GPU. After moving to a newer CPU model, it made a huge difference. If you're looking for an upgrade, something like a Ryzen 7 5800X3D could help balance things out without completely redoing your setup.
Yeah, definitely keep in mind future-proofing your setup. Buying high-end now can save you money later. Just consider if you really need that performance for the games you play.
Right? I noticed improved performance after I installed a fresh version of Windows too. It might be worth trying before making any drastic decisions.
