I'm currently running an RX 7900 XT with a Ryzen 9 5900X, and I've noticed CPU bottlenecks in some games. Titles such as Escape from Tarkov and Where Winds Meet perform worse than I expected, even though the GPU should be powerful enough. I'm also considering moving to a 1440p display. Would it make more sense to upgrade the monitor first, or would replacing the 5900X with a Ryzen 7 5800X3D provide a worthwhile improvement? I'd prefer to stay on my current AM4 and DDR4 platform rather than move to DDR5, especially since I already have enough memory.

I’d try the 1440p monitor first and then reassess. At a higher resolution, more of the workload shifts to the GPU, so the 5900X may feel perfectly adequate depending on your frame-rate target. An OLED 1440p display would pair nicely with the 7900 XT, and you may find that the CPU upgrade is less urgent afterward.
Before buying anything, monitor CPU and GPU utilization in the specific games giving you trouble. If one or two CPU cores are maxed while the GPU is well below full usage, the 5800X3D is a sensible drop-in upgrade. If the GPU is already near full utilization, a new CPU probably won’t improve performance much. The 5800X3D is one of the best ways to get more gaming performance without replacing your motherboard, RAM, and platform.
If the games are genuinely CPU-limited, the 5800X3D can make a very noticeable difference over the 5900X, especially in simulation-heavy or poorly optimized games. I made a similar upgrade and saw a clear improvement. Just keep in mind that a faster graphics card later could expose another CPU limit, so this is mainly worthwhile if you want to extend the life of your current AM4 platform.
That’s exactly why I’m considering it. I recently upgraded other parts without realizing the CPU might still hold things back, and I’d rather avoid the cost of moving to DDR5 when my current RAM is already fine. I’m mainly trying to figure out whether the 5800X3D is enough of an improvement to justify buying one.
I agree with checking the monitor and resolution first. If you move to 1440p or even 4K, the GPU should be doing more of the work, which could reduce the bottleneck and show whether a CPU upgrade is actually necessary.
