Qwen3.6 35B (3B active)

User reports Qwen3.6-35B-A3B at 35 t/s on an RX 7800 XT 16GB, with a Ryzen 5 7600X and 32GB DDR5. Setup is llama.cpp with UD-Q5_K_M (about 25GB), which spills past the 16GB card. User asks whether to swap to a used 7900 XTX 24GB or add a used 7600 XT 16GB, and requests real t/s numbers for either setup under Vulkan or ROCm.
