With regards to AI?. None tbh.

TBH, that might be enough. Stuff like SDXL runs on 4G cards (the trick is using ComfyUI, like 5-10s/it), smaller LLMs reportedly too (haven't tried, not interested). And the reason I'm eyeing a 9070 XT isn't AI it's finally upgrading my GPU, still would be a massive fucking boost for AI workloads.
