▸Value verdict

▸ Should you buy/upgrade?

A6000 Pro adds 8 GB VRAM for the same price. The real question is whether your workflow needs models that A100 40GBcan't run.

If yes — you want to run Llama 4 Scout 17B 16E or similar — then the 8 GB is load-bearing, not luxury.

$ recommend → If you own a A100 40GB: wait. Prices drop, refresh cycles continue. If buying new: get the A6000 Pro IF your budget allows AND you need the unlocked models.
