Decision rule
Start with memory and workload fit
Start at 24GB when AI video is serious, and move to 32GB+ when the buyer wants more room for larger models, longer clips, and heavier experiments.
AI video GPU path
GPU shopping lanes for local AI video workflows
Video workflows can stress the whole workstation, not just the graphics card. Use this guide to start from VRAM and sustained-load readiness before opening Amazon.

VRAM pressure
Why this workload gets expensive
AI video can raise memory pressure through frame count, resolution, model choice, temporal settings, and post-processing.
Avoid this mistake
Do not buy on model name alone
Avoid a cramped case or marginal PSU for a high-VRAM card that will run sustained workloads.
