A Reddit user discusses upgrade paths for running Qwen3.8-27B, starting from an RTX 5080 and Ryzen 9 9950X3D. The analysis covers motherboard upgrades for PCIe 5.0 support and compares the cost-efficiency of adding an RTX 5060 Ti 16GB (32GB total VRAM) versus multiple used RTX 3060 12GB cards (40-52GB total VRAM), weighing heat, power, and price. Future plans for pro cards and system RAM expansion are also considered.
