Building a $2,000 CAD ComfyUI PC: used RTX 3090 24GB vs newer GPUs?

A Reddit user asks for advice on a $2,000 CAD desktop build in Canada for ComfyUI and local AI workflows: image generation (FLUX/SDXL), AI video and 4K upscaling, running larger models locally, and Blender rendering. GPU candidates are a used RTX 3090 24GB vs a new RTX 5060 Ti 16GB, with 64GB system RAM planned. Key questions: is the 3090 still the best value for its 24GB VRAM, would a newer 16GB card actually be faster in ComfyUI, and what CPU/motherboard/PSU to pair, prioritizing real-world performance, VRAM, stability and upgradeability over gaming.
