I've actually tried this exact same model locally as well.. albeit on just a single 3090 at 128k context and I got around 40-60tok/s with Q4_K quantization.
The thing that bugged me the most was really the quality of the output on moderately complex real-world coding tasks. Having to switch between "prompt/vibe" and "manually implement" is such a big context switch burden, because you really have to ask yourself every few minutes if you're "holding it wrong" or the model is just too stupid.
It also doesn't really seem to handle transitions from "low-level implementation detail" to "high-level design" well, e.g., it wouldn't easily render tables and such. With Claude I don't have this issue.. so I think for now my verdict would be that it's not really a viable replacement. I really hope it will be in a few months time.
Oh and I used "aider" to replace claude CLI, which maybe that's also sub-optimal.. I'm not sure. The MCP marketplaces are useful of course, though arguably you could just manually replace them over time.
