My current system has a Ryzen 7 5800X, a Radeon RX 9060 XT 16GB, 32GB of RAM, and a B550 Gaming X WiFi 6 motherboard. I play at 1080p and 144Hz, and I sometimes notice what seems like a CPU bottleneck when running certain games alongside OBS and VTube Studio while streaming. Would switching to a Ryzen 7 5800X3D make a meaningful difference, particularly to average FPS, frame-time consistency, and 1% lows, or would the two processors perform too similarly? I know the upgrade keeps me on the end-of-life AM4 platform, but moving to AM5 is currently far too expensive, while the 5800X3D costs about €329.

At €329, it is not automatically a great value for every 5800X owner, but it is still much cheaper and simpler than replacing the motherboard, memory, and CPU. For a 1080p high-refresh setup with streaming and CPU-limited games, the 5800X3D is one of the few upgrades that can provide a clearly smoother experience without moving to a new platform.
For games such as large multiplayer titles, racing games, or games that depend heavily on a main thread, the upgrade is likely to be noticeable. People commonly report fewer stutters and much better minimums after moving from a 5800X to a 5800X3D, even at higher resolutions. At 1080p, the difference is more likely to show because the GPU has less work to do.
The 5800X3D can definitely improve performance, especially at 1080p and in games that are sensitive to cache or rely heavily on one or two CPU threads. The biggest improvement may be smoother frame pacing and better 1% lows rather than a huge average-FPS jump. Streaming software can also expose CPU limits that do not always show up as 100% total CPU usage, since one or two cores may be saturated while the rest are relatively idle.
It is a sensible end-of-platform upgrade if you intend to keep the rest of the system for several years. Before buying, test the games that actually cause problems with and without streaming, and watch GPU usage, per-core CPU usage, frametimes, and OBS dropped frames. If the GPU is regularly below full utilization while a core is maxed out or frametimes are uneven, the 5800X3D should help. Selling the 5800X would also reduce the effective upgrade cost.
Do not expect the same improvement in every game. Some titles will barely change, and if the issue is simply that the game, OBS, and VTube Studio are competing for CPU cores, another eight-core processor may not completely solve it. Make sure OBS is using hardware encoding on the graphics card if available, and check whether the problem is rendering lag, encoding lag, or an actual game-side CPU limit.
That is an important distinction. If OBS reports encoding or rendering lag rather than the game losing performance, changing the CPU may not be the right fix.
Exactly. A CPU bottleneck is not always obvious from overall utilization. Check per-core usage, GPU utilization, frametimes, and performance with OBS and VTube Studio running together.
