Building a Multi-GPU Deep Learning Machine on a budget

After all, not even the biggest and most powerful from NVIDIA's current lineup, the RTX 3090, manages to saturate a PCIe x16 connection

We recommend a minimum of 8 PCIe Gen 4 lanes per physical x16 slot on the motherboard for a four-GPU build You may use fewer GPUs and populate the empty PCIe
