With 128 GB strix halo, you can't do as big of a model as you would think. You can do larger than having a single graphics card, of course, but that 128 gigs cannot all be dedicated to the model. Remember, the context alone is usually larger than the model itself. I got an EVO X2, and I don't regret it, but by my current calculations, it will take 8 years to recoup the cost, as opposed to just using equivalent, paid commercial options.
A key consideration in favor of running your local LLM despite all the trouble: The commercial serving endpoint may not exist tomorrow, or at least not at the same price.
