It's a hijacked account. You can look at the sales history for that item and their feedback. The item # is 133431063423 and they received feedback for that item ID when the listing had a title of "nagelverlängerung modellierschablonen". Those are nail extensions, not GPUs...
Obvious scam is obvious.
Price is way too good to be true, even for a panic sale due to RTX 3000.
Payment only via bank transfer.
Seller previously only sold totally different items.
Reading the item description is pretty hilarious too. Some SOB story about financial difficulties due to the pandemic. Creating false urgency by claiming that the price will only last for a few hours
