For those looking for a 3090, this is a pretty good way to go. It’s from the manufacturer and not some random person on ebay. Just regular used 3090s sell for over $800 on ebay now. This is a 3090ti and comes with a 2 year warranty from the manufacturer.

If you are looking for a regular 3090 for less money. They also have those as low as $711 but they are OOS right now. So launch a bot and have it watch that page like a hawk. Since when they do drop stock, it’s like BF and over in seconds/minutes.
