The price gap has closed considerably. When DDR5 launched the premium was absurd - you were paying nearly double for marginal real-world gains outside of memory-bandwidth-limited workloads.
Now the gap is maybe 20-30% depending on kit. So the question has shifted from "obvious no" to "depends on your use case."
Where DDR5 actually helps:
Where DDR4 is still fine:
My take: if you are buying new today, get DDR5. If you have DDR4 and it is working, do not upgrade just for memory.

Where DDR5 actually helps:
- CPU-bound gaming on Alder/Raptor Lake and newer - measurable but small (3-8% in most titles)
- Compilation workloads and anything parallelism-heavy
- If you are building new anyway - the platform longevity argument is real
Where DDR4 is still fine:
- GPU-bound gaming (vast majority of people)
- Existing AM4 or older Intel builds
- Tight budget builds where that 20% goes to a better GPU instead
