They're 2080 Supers, not 2080 Tis. And apparently, RAM upgrades just aren't cheap/easy/possible ATM either way. But if those RAM upgrades were a thing, then I think these cards might max out at 16GB instead of 22GB, as that represents a natural doubling.

For what they are, as they stand: You'd be safer and better-protected to buy one from eBay for ~$200 USD than to get one from some rando on the internet, like me.
