No, it won't cause a bottleneck. The 2080 Super supports 1080p and should handle the 5900x resolution without issues.

Hello everyone, I believe the title covers nearly everything. I’m curious if my GPU might be limiting my CPU performance, as I’ve heard many people experience this issue with certain GPUs paired with older CPUs.
I was thinking about pairing my 2080 Super with the 5900x after hearing many online comments suggesting it might be a bottleneck. Curious if that’s actually true.
You're limiting your CPU performance. However, this phrase is often repeated too much. In reality, your CPU can handle more frames per second than your GPU can process. That's what creates a bottleneck. Adding a 3090 would likely boost your FPS even further. This isn't a problem—it simply means you could achieve higher performance with other components. Every system has some limitations; if it had none, you'd see unlimited FPS. You're probably seeing over 150 FPS in most games, which is excellent.
Relies heavily on the software or games you're using. Every title is unique. Keep in mind you have a fairly well-rounded setup—just follow what works for you and ignore outside opinions, except from this discussion. We’re listening.
I posed this question before my 5900x had a 3600x paired with it, and I was worried that the bottleneck might be too large, making it better to stick with my older 3600x instead of the new 5900x. Probably just fearing I wouldn’t get any extra performance after spending $500 on the CPU.
That’s not the usual way things are handled… technically your GPU is limiting performance now. However, a slower CPU won’t necessarily improve things; your GPU will still be the main constraint with your 3600x. A quicker CPU would likely boost FPS more effectively. Many people misunderstand this. The key is finding the best balance. An i3 and i7 might both limit a 3090, but a higher-end CPU like an i9 or 5900x would give better results. The cost difference often doesn’t match the performance gain. An i3 paired with a 3090 feels out of place since you invested heavily in the GPU. Similarly, a 5900x and GTX 970 don’t fit the same logic. So yes, your GPU restricts the full power of your 5900x. But reverting to a 3600 would probably drop you around 5-10% in FPS. I’d think it makes more sense to upgrade the GPU for higher FPS rather than the CPU, though a 2080 still has its place.
You're absolutely correct! The main limitation comes from whether the CPU and GPU are comparable, especially with overclocking. A 1080P display on an 2080s card is simply too slow for that resolution. Going for 4K at 60fps would really push the system to its limits and provide a great challenge.
Typically when the CPU struggles with the GPU, it's usually the opposite situation. A bottleneck often causes lag rather than the other way around. The 5900x is one of the fastest gaming CPUs available, but I wouldn't rush upgrading a 2080S unless you're playing niche titles (just kidding). This video shows a single-core and RAM bandwidth issue at 1080p, with GPU limitations for higher resolutions like 1440p+ or 4K at 120Hz. The problem is why I'm holding off on a GPU upgrade, and I'm confident your CPU can manage next-gen GPUs easily.
