A user is seeking advice on building a server for local large language model (LLM) inference, specifically debating between purchasing four RTX Pro 4500 GPUs or four used 40GB A100 GPUs. The RTX Pro 4500 option would require a PCIe switch, adding complexity, while the A100s would necessitate NVLink bridge adapters and carry the risk of purchasing faulty hardware from eBay. The user is in a hurry to make a decision due to a return deadline for previously purchased Intel B60 cards, which proved unsuitable for scaling. AI
