I'm considering replacing my Intel Core i9-9900K with a Ryzen 7 9850X3D. Gaming performance has felt worse lately, and the system also seems sluggish and runs fairly hot. I use three monitors—one at 1440p and two at 1080p—and often multitask while gaming. In games such as League of Legends and Counter-Strike 2, I'm sometimes below 100 FPS even at medium or medium-high settings, and I'd like to play more demanding titles as well.
A local store has a bundle for about $900 that includes the Ryzen 7 9850X3D, an ASUS B850E TUF Gaming WiFi6E motherboard, and 32GB of DDR5-6000 memory. My current power supply, cooler, and RTX 4070 Ti should be compatible with the new system. I can afford the upgrade, but I'd like to know whether it would provide a substantial real-world improvement or whether I should troubleshoot my current setup first.

A newer X3D processor, DDR5 memory, and a modern motherboard would give you a much stronger and more responsive system overall. The biggest gains will appear in CPU-bound games, high-refresh-rate gaming, minimum FPS, and multitasking; at higher resolutions where the 4070 Ti is the limit, the improvement may be smaller.
The price seems reasonable if you want a long-term platform upgrade and the bundle includes the exact parts you need. Just make sure the cooler has the correct AM5 mounting hardware, update the motherboard BIOS if necessary, and confirm that 32GB is enough for your multitasking workload.
That would be a major platform upgrade from a 9900K, especially for CPU-limited games and multitasking. People moving from older Intel systems to an X3D chip have reported noticeably smoother performance and higher frame rates, so the upgrade should be apparent with a 4070 Ti.
The upgrade should help, but your current performance also sounds worth investigating before spending $900. Check CPU and GPU temperatures, clock speeds, background applications, memory usage, thermal throttling, and whether the displays are connected and configured properly. Running several monitors and multitasking can add some load, but it normally shouldn’t explain unusually low FPS by itself.
