My i9-14900K has been running for a little over two and a half years and was stable until recently, despite installing the latest BIOS and microcode updates. Now Windows updates consistently trigger BSODs, and I also get occasional crashes while browsing. MemTest86 passes, the storage drive appears healthy, and I recently performed a fresh Windows installation, so I suspect the CPU may be failing. I have started an Intel RMA, but I'm considering buying a Ryzen 7 9800X3D and motherboard bundle for about $450, then selling the replacement Intel CPU and my Z790 motherboard. The system is used almost entirely for 4K gaming with an RTX 4090, and I already have 96GB of DDR5-6800 memory. Would switching to the 9800X3D be a worthwhile move, or should I keep the replacement Intel system?

For a gaming-focused build, the 9800X3D is a very reasonable swap, especially since you already have DDR5. AM5 also gives you a better upgrade path for future processors. Just expect that your 6800 MT/s memory may need to run closer to 6000 for stability, depending on the motherboard and memory controller.
Another option is to complete the RMA and keep using the replacement system until the next generation of X3D chips arrives. The 14900K is still a strong gaming processor, and moving to the 9800X3D won’t transform 4K performance in every title. However, if you value stability and the bundle price is good, buying the AMD setup now and selling the replacement Intel parts is a sensible approach.
The 9800X3D is relatively easy to cool compared with the 14900K. A decent dual-tower air cooler or a basic 240mm AIO should be enough, provided you have the correct AM5 mounting hardware. Your existing Ryujin III would work if you can obtain its AM5 brackets; otherwise the included cooler should be adequate.
I’m planning to complete the warranty replacement either way, then sell the unused replacement CPU and my Z790 board to offset the cost of the new platform.
