Which GPU should you buy for Stable Diffusion and Flux? The pick for every budget
For most people in November 2026 it's an RTX 5060 Ti 16GB: it runs SDXL and FLUX.1-dev in ComfyUI for about $549. Below that a 12GB RTX 3060 still works, a used 24GB RTX 3090 holds all of Flux in memory, and the 32GB RTX 5090 is the fast, scarce top end. Prices and timings dated and sourced.
