One user's local AI rig: DGX Spark bandwidth disappoints, RTX Pro 6000 looks like a steal

- The author recounts how the local AI hardware landscape changed over 1.5 years, listing his rig: RTX Pro 6000, RTX 5000, 2x DGX Spark, M4 Max, and M4 Pro.
- Key observations: DGX Spark's memory bandwidth is poor — its CUDA cores can't shine, and even an M4 Max has double the bandwidth; MoE + speculative decoding advances are making high-RAM non-RTX-Pro systems increasingly capable. He thinks the RTX Pro 6000 would be an insanely good deal at $6-8k.
