You can't run deepseek-v3/r1 on the RTX Pro 6000, not to mention the upcomming 1 million context qwen models, or the current qwen3-235b.
Practically, last gen or even ES/QS EPYC or Xeon (with AMX), enough RAM to fill all 8 or 12 channels plus fast storage (4 Gen5 NVMEs are almost 60 GB/s) on paper at least look like cheapest way to run these huge MoE models at hobbyist speeds.
