You can run one on 850, up to you. The price difference isn't massive for that model, compared to potential future utility if you go mega on the card later.whats the best psu for a 5080 still 1200W I have or can reduce it?
If you can wait for the 5080 Super, I would, since if it has the extra VRAM that could be very useful, especially if you progress to 4K at some point.
