I'm putting together a new gaming PC, but the total cost is already much higher than expected. Choosing 16GB of DDR5 for now would save me around €300, and I could upgrade later once I have more money. Would 16GB be enough to play most games comfortably in the meantime, or is 32GB effectively necessary for a system with these specifications?
The planned hardware is an RTX 5070 Ti with 16GB of VRAM, a Ryzen 7 9800X3D, and a 750W power supply. If I start with 16GB, should I use one 16GB stick, a 2x8GB kit, or replace the memory entirely when upgrading?

You may be able to balance the budget better by choosing a less expensive CPU or switching from the 5070 Ti to a similarly performing Radeon card. That could free enough money for 32GB immediately. For gaming, 32GB is likely to be a more useful quality-of-life upgrade than spending extra for the very highest-end parts.
Try to keep the system to two DIMMs. On this AM5 platform, four DDR5 sticks can be harder to run reliably at higher speeds and may force you to reduce the memory speed or loosen the timings. The ideal long-term setup would be a matched 2x16GB kit, preferably around DDR5-6000 with sensible timings.
There is no urgent need to panic if you start with 16GB. Thousands of games will run well, and the 16GB of VRAM on the graphics card can help in some situations. Just expect less comfortable multitasking and plan to upgrade sooner rather than later. If you already know you will upgrade, buy a temporary 2x8GB kit and sell it when you move to a matched 2x16GB kit.
Yes, 16GB will get you through most games, especially if you are only running the game and a few background apps. However, it is becoming the minimum rather than the comfortable amount. With Discord, a browser, recording software, or newer demanding games open, you may see stutters or worse frame-time consistency rather than simply lower average FPS.
If you need temporary memory, a 2x8GB kit is better than one 16GB stick because it preserves dual-channel operation. When you can afford 32GB, replace that kit with 2x16GB rather than adding another 2x8GB kit.
