▸Value verdict

▸ Should you buy/upgrade?

RTX 5090 adds 8 GB VRAM for +$199 (9% premium). The real question is whether your workflow needs models that L4can't run.

If yes — you want to run deepseek r1 distill llama 70b or similar — then the 8 GB is load-bearing, not luxury.

$ recommend → If you own a L4: wait. Prices drop, refresh cycles continue. If buying new: get the RTX 5090 IF your budget allows AND you need the unlocked models.
