I have a budget-oriented 2021 PC with an Intel i5-9600K, 16GB of DDR4-2666 memory, a GTX 1660 Ti, and an Asus Prime Z390-A motherboard running Windows 10. It still feels fast for everyday use, but it is becoming limiting for my interests: small-scale game development with Unity and Godot, Adobe applications, high-resolution digital art, and eventually Unreal Engine. Shader compilation, editor performance, and VRAM usage are already noticeable problems, especially since the GTX 1660 Ti only has 6GB of VRAM.
I had planned to upgrade in a year or two, but rising component prices have me worried that waiting could make a capable system unaffordable. I cannot spend thousands on a complete build right now, so I am considering buying a 16GB RTX 5070 Ti while I can and building the rest of the system gradually over the next six months to two years. Does that make sense, or is this mostly FOMO and anxiety? Would a newer GPU work properly in my current motherboard, or would I need to replace the platform immediately?

I would not buy an expensive part solely because you are afraid prices will be much worse years from now. GPU pricing has been unpredictable, and nobody can reliably forecast what a 2028 card will cost. Buy a card if it solves a problem you have today, but do not stretch your finances for a future build that may use different hardware by the time you finish it. If the 5070 Ti is barely affordable, a less expensive 16GB card could be a more sensible stopgap.
If you need more performance now, upgrading only the GPU is the simplest and most cost-effective move. You can keep using the current PC and transfer the card into a future build later. Just check your power supply, case clearance, and the card's power connector before buying. I would also consider moving to 32GB of RAM when practical, since game engines and creative applications can use more than 16GB fairly easily.
You do not need to replace the motherboard just to install a newer graphics card. Modern GPUs are backward-compatible with PCIe, so a newer card should run in the Z390-A's PCIe slot. You may lose a small amount of performance in some situations, but the bigger limits are likely to be the 6GB of VRAM, 16GB of system memory, and the older six-core CPU. A GPU upgrade could still make a very noticeable difference, especially for Unreal, modern games, and GPU-accelerated Adobe work.
You could also make a cheaper platform upgrade while keeping your DDR4. Some older Intel LGA1700 systems can use DDR4 memory, letting you move to a newer CPU and motherboard without replacing everything at once. However, that platform is already at the end of its upgrade path, so it is mainly worthwhile if you find a good deal. For a longer-term build, save until you can move to a current platform with 32GB or 64GB of memory rather than buying parts years apart.
The GPU is definitely the part running into a hard limit first for me because newer games and Unreal are pushing past 6GB of VRAM. I may upgrade that now and wait on the CPU and motherboard until I can afford a complete platform change.
That clears up the PCIe concern. My GPU and CPU both sometimes hit 100%, and Unreal frequently warns that I am exceeding the 6GB VRAM limit, so the graphics card seems like the most obvious immediate problem.
