I bought a Ryzen 9 5900XT about a year and a half ago after my 5900X failed. At the time, I used the same PC for gaming and streaming, so the extra cores made sense. I now stream from a separate system and am considering switching to a Ryzen 7 5800X3D, currently available for $299.99. I could sell the 5900XT to reduce the overall cost. My average frame rates are already good, but I want smoother gameplay and better 1% lows, especially on a 240Hz monitor. My system has a Ryzen 9 5900XT, Radeon RX 9070 XT, 32GB of DDR4-3600, and runs games at 1440p. I mainly play Halo: The Master Chief Collection, Halo Infinite, and Dragon Ball Gekishin Squadra. Would the 5800X3D noticeably improve frame-time consistency, or should I keep the 5900XT and save for a newer platform?

The XT naming is easy to confuse here. AMD did release a Ryzen 9 5900XT CPU; it is a higher-clocked model positioned between the 5900X and 5950X. It is not the same naming scheme used for AMD graphics cards, so the processor model in the setup is plausible.
I would have a hard time paying $300 for a sidegrade unless the stutters are genuinely bothering you. The 5900XT is still a strong processor, and the 5800X3D gives up two cores and productivity performance. If you can sell the 5900XT for a good price, the swap becomes more reasonable; otherwise, saving for a newer platform may offer a more meaningful long-term upgrade.
The 5800X3D is specifically good at improving frame-time consistency and 1% lows, so it could help if your games are CPU-limited. With a powerful RX 9070 XT and an unlocked frame rate at 1440p, the 5900XT may hold the GPU back in some situations. Before buying, check whether the GPU is reaching close to full utilization during the moments where the lows bother you.
I moved from a 5900X to a 5800X3D with a high-end graphics card and noticed a major improvement in gaming smoothness, particularly in the lows. It made sense for me because gaming was the priority and I was willing to spend the money. Productivity workloads such as virtual machines and decompression were slower, though, so the tradeoff is worth considering even if streaming is no longer part of your setup.
The value depends heavily on the final cost after selling your current CPU. A cheaper X3D option, if compatible with your board and available locally, could provide some of the gaming benefit for less money. Otherwise, keeping the 5900XT and putting the money toward a future platform upgrade is probably the safer choice.
