I currently have an RTX 4090 paired with a 10900K CPU and I game on a 1440p ultrawide monitor (3440x1440). I'm planning to upgrade to a 5K2K resolution, which will definitely put my GPU at a bottleneck. I'm considering upgrading a few components including my CPU from a 10900K to a 9800X3D (which has fewer cores but features 3D V-Cache), as well as my motherboard to support PCI 5.0, and switching my SSD from PCI 3.0 to PCI 5.0. Lastly, I'm thinking of upgrading my RAM from DDR4 to DDR5. Will these upgrades provide a meaningful performance improvement even with the GPU bottleneck? If so, what kind of performance boost might I expect?

It might help your 1% lows, but I wouldn't count on too much. It could be better to upgrade your monitor first and then evaluate how it performs before making further changes.
Definitely, you'll notice an improvement! Expect better performance mainly in the 1% lows and maybe a slight increase in overall frames, especially when playing at higher resolutions like 4K.
Your expectations should really depend on the games you play. Given the upgrades, you could see around a 10fps boost overall. However, remember that if you're using DLSS, the GPU handles tasks differently and may provide a bigger impact on performance under those conditions.
While the 9800X3D should give you better 1% lows due to its cache, don't expect drastic changes in average FPS. You might want to hold off a bit and wait for future GPU generations, as the return on investment could be more worthwhile down the line.
When moving to 4K, you might not see significant changes compared to your current setup. The difference could be minor, around 1-3% with the new specs, particularly on a high-end card like the 4090. The gains would be more noticeable in lower-res settings. I'd suggest benchmarking after any upgrade to see actual performance before and after.
