I'm currently using a Ryzen 5 5600X, 32 GB of RAM, and a Radeon 9070 XT with a 3440×1440 ultrawide monitor. The system performs well, but after connecting it to a 4K TV, I noticed that my frame rate was surprisingly similar. That made me wonder whether the 5600X is limiting the GPU in some games.
I'd like to spend carefully and avoid buying into AM5 if it means replacing the platform again when AM6 eventually arrives. A Ryzen 7 5800X3D costs around €360 where I live, which feels expensive for a last-generation AM4 upgrade. Instead, I'm considering a Samsung Odyssey G7 with a 5120×2160 resolution. Would moving to a much higher-resolution display meaningfully address the CPU limitation, or would it simply create a GPU bottleneck and reduce performance?
My thinking is that upscaling technologies such as FSR may improve over time, letting the 9070 XT handle that resolution for longer. I'd appreciate advice on whether a CPU upgrade, a different display, or simply keeping the current setup makes the most sense.

A higher-resolution monitor won’t remove the CPU bottleneck; it usually shifts the workload toward the GPU. That can lower your frame rate, but it isn’t really an upgrade in performance. Also, check the refresh rate of the TV before drawing conclusions—many 4K TVs run at 60 Hz, so the display may be limiting what you notice. I’d prioritize the CPU only if you’re actually failing to reach the frame rates you want.
If you want to stay on AM4, an X3D chip is the sensible upgrade, but €360 for a 5800X3D is hard to justify unless your games are clearly CPU-limited. Look into a cheaper 5600X3D or similar option if it’s available, and undervolting can help keep temperatures and power use under control. Otherwise, keep the 5600X and save for a full AM5 platform upgrade later instead of buying an expensive end-of-line CPU.
A 5120×2160 display is a huge jump in pixel count and would put considerably more pressure on the 9070 XT. It may be worthwhile for image quality or workspace, but it won’t solve a performance problem, and you’d likely rely heavily on upscaling or reduced settings. Buy that monitor because you want the sharper, larger display—not as a way to balance the CPU and GPU.
Don’t assume the same FPS automatically proves a CPU bottleneck. Compare GPU utilization, per-core CPU usage, and frame times in the same game and settings. A 3440×1440 ultrawide is already fairly close to 4K in total pixels, so similar results between those displays are expected. If you’re already getting the refresh rate you want, cap the FPS and keep using the system rather than upgrading just to eliminate a theoretical bottleneck.
For competitive games, the CPU can matter more because they often run at very high frame rates. In that case, a higher-refresh-rate monitor may be more useful than jumping to an extreme resolution.
