Short answer

Best quantization for chat: 4-bit (150 GB of weights) on LM Studio. Generation: 35–45 tok/s, leaving about 31 GB free for your other apps.

How it rates for each workload

Same model and machine, different jobs. Agents and long documents send far bigger prompts than chat, so they need much more speed and memory.
