A user wants to add a second 16GB VRAM GPU (5060 Ti or 5070 Ti) to their MSI X670E Tomahawk WiFi motherboard for running large local LLMs like Qwen 3.6 27B. The current setup lacks space for a second GPU due to the primary 5070 Ti occupying the second PCIe slot, leaving only the third slot partially available. The user seeks advice on feasible options—such as using the fourth PCIe slot or a riser—while considering cooling, stability, and physical fit, especially with a horizontal GPU mount like the Lian Li VG4v4.
