VRAM Whisperer: Auto-Optimize ComfyUI Offload & GPU Buy Decisions

Detailed ComfyUI native-workflow benchmarks show that VRAM alone is not the only factor for image/video generation performance; measured PCIe/RAM offloading, torch compile, and GPU compute differences (CUDA cores, FP4 acceleration) determine real-world results and inform buying recommendations for 30/40/50/60-series GPUs.
