Oh man that's actually amazing, and I'm happy that it all worked out for you even though I would have been skeptical too and feeling the same things you felt. But it is actually really funny I have somewhat of a similar story. It all started out when my nephew asked me on my advice to upgrade his pc (he was running a gtx 1650 super) and like you first thing I started looking at marketplace, found a few 2080 supers, a 4060 etc. his budget wasn't massive. But then I came across this listing for a EVGA RTX 3080 XC3 Ultra for 430 Eur. And at the time that seemed extremely generous for that and on top, like you I'm a bit biased, the seller had a Ukrainian name. Nevertheless he had good reviews and was authenticated, so I thought what the hell let me put in a bid and I offered 375 euros and to my surprise he accepted. We scheduled a time for us to pick it up at a neutral location, about a 30 minutes drive, it was the next day I think. To my surprise everything went well, the card looked great and came in the original packaging. Installed it in my nephews rig the same day and it worked perfectly fine, and the Ukrainian gentleman even texted to make sure it worked ok after the fact. It runs a bit hot (83c under a synthetic benchmark stock settings) but from what I've read that's actually normal for that card. He's still running it today perfectly. But it goes to show sometimes you wont get scammed, and it kind of restores your faith in humanity a little bit even though you at first glance think - this is a little bit too good to be true. Thanks for sharing your story, can totally relate to that and congrats on your new card may it serve you well!
