Is it worth getting a GPU with ECC (error correction)? I don't know if GPU's regularly come with the equivalent of "hot" or "dead" pixels like camera sensors, but that doesn't matter as much in pictures and games as getting a perfect AI output without compounding errors. RTX Pro x000 series are the AI specific GPU's, though they are of course more expensive. Google AI says the 4000 is better than the 3060, but worse than the 3090 performance wise. I'm not sure how important ECC is.
