I'm currently using a Ryzen 9 3900X with an X570 Aorus Elite motherboard, 64GB of DDR4-3200 CL16 memory, and an RX 6900 XT. I game at 3440×1440 and also use AutoCAD, ETABS, Revit, and Excel. With around $300–$400 available, would it make more sense to replace the 3900X with a 5700X, 5800X, 5900X/5900XT, or 5950X? Should I instead sell my current parts and move to a newer platform, and roughly how much would that upgrade cost?

A 5700X is the best value choice if saving money is the priority. It should be easy to install on your existing board and will still provide a noticeable improvement in gaming smoothness and general responsiveness. For your professional applications, though, a 5900X, 5900XT, or 5950X would offer more benefit because they retain more cores.
Moving to a newer platform would mean replacing the CPU, motherboard, and DDR5 memory, so the total cost would be much higher than $300–$400 after selling your current parts. At 3440×1440 with an RX 6900 XT, a CPU upgrade may not transform gaming performance anyway. I’d keep the current platform and buy the fastest reasonably priced compatible processor, ideally a used 5900X or 5950X.
If you want to keep costs under control, a used 5950X is probably the strongest drop-in upgrade. You can keep the X570 motherboard, 64GB of DDR4, and your RX 6900 XT, while gaining a substantial boost in heavily threaded CAD and engineering workloads. It also lets you postpone replacing the entire platform until you actually need to.
I’m mainly trying to save money right now, and I have about $300–$400 available. That makes a drop-in upgrade sound more realistic than replacing the whole platform.
