I've been gradually upgrading the same PC since around 2018. The current build has a Ryzen 7 3700X, MSI B450 Tomahawk, 32GB of DDR4-3600 memory, a 500GB SATA M.2 SSD, an RTX 4070 Super, a Fractal Meshify C case, and a 650W Gold-rated power supply. I also have several SATA drives and a PCIe USB expansion card because the case's front I/O ports no longer work.
The RTX 4070 Super is still more than sufficient for my needs, so I'd rather not replace it. Before losing my job, I planned to upgrade the CPU to a Ryzen 7 5700X3D and eventually move the system into a newer case with a new motherboard and power supply. Now that I'm considering a motherboard replacement, moving to AM5 seems more logical, but the cost of buying a new motherboard, CPU, and DDR5 memory is difficult to justify.
What would be a worthwhile upgrade I can make now that improves performance but could still be useful in a future rebuild?

The Ryzen 7 5700X3D is probably the most sensible upgrade if you can find one at a reasonable price. It works with your existing B450 board and DDR4 memory, giving you a substantial gaming uplift without forcing you to replace the platform immediately. A 5800X3D would also work, but it is usually too expensive to make sense compared with newer options.
I wouldn’t switch to an Intel platform just to reuse your current DDR4. You’d still be buying a new motherboard, and that route doesn’t give you the same straightforward drop-in upgrade as staying on AM4. If you eventually rebuild, save for AM5 and DDR5; for now, an AM4 CPU upgrade lets you postpone that expense.
If you happen to have access to a bundle deal, a newer platform can be good value, but without one the total AM5 cost is hard to justify when the 4070 Super is still doing fine. Your current motherboard can support an upgraded Ryzen 5000 processor after a BIOS update, so check compatibility and BIOS requirements before purchasing.
If you want to spend as little as possible, a Ryzen 5 5600 or 5700X can reduce the CPU bottleneck and extend the life of the system. The 5700X is a reasonable step up from the 3700X, but the X3D chips are a much more noticeable gaming upgrade. Since your graphics card is already strong, I’d prioritize the CPU rather than replacing other parts.
