I built a dual R9700 rig. Looking for advice.

I built a dual R9700 rig over the weekend. I’ve spent a few hours running standard admin tasks on Ubuntu Server so it’s ready to roll. I’m hoping my fellow dual R9700 folks will share their setup as sort of a megathread to help me and others who may follow this path.

The advice I seek:

- inference engines
- fine tuning
- performance tuning
- TP vs PP over x8/x8 bifurcation
- common pitfalls
- models that fit well
- models that don’t fit well
- hosting multiple models
- observability stack
- monitoring stack
- storage and backups
- any other advice you might have to give
