$400 Qwen 3.6-27B Setup - Dual RTX 3060 - 30-50 t/s

I picked up a 7900 XTX earlier which runs qwen3.6-27b fine, but not to my like. Its compute performance is quite unstable for me. With MTP the decode speed can reach 40-60 t/s, but prefill is just too slow. Regardless of whether I used ROCm or Vulkan, the prefill speed varies between 300t/s and 500 t/s, even with very long prompts. I've been itching to try out an ultra-budget 24GB setup using dual 3060s. I managed to snag a second 3060 at a reasonable price in last few days. So I took out the 7900 XTX, installed the 3060s, and began testing.
