Buying Priority

What matters most for this workflow

This workflow keeps multiple models resident at once, so memory headroom matters more than chasing the cheapest possible card.

Practical Tradeoff

How to think about the hardware

This is one of the cleaner local-first cases: if you use the tools regularly, the economics catch up quickly and privacy/offline access become a bonus rather than the only justification.
