Require a 4070 (not-70Ti, but S and TS are both welcome) or 4080 for LLM and Stable Diffusion. Warranty highly preferred, even if it is on the short side. One week testing warranty also needed. Budget is 35-55k depending on model, warranty and condition of card. Beggars can't be choosers, but I'd like to stay away from Zotac, Galax and Inno3D if possible. Need a good card that can run long hours without breaking a sweat.
