I wouldn’t be so sure, a good friend of mine ordered a GPU and it was an older and much cheaper model with the shroud replaced and flashed to call itself the newer model in windows. He would not have found out except he immediately ran a benchmark that returned an extremely low score and then investigated from there.
Additionally, there is fear that you receive the "actual item," but it has been used detrimentally (usually: operated 24/7 too hot) for cryptomining or genAI.
This actually happened to me once (VEGA64) and I was surprised when Amazon authorized a full refund after the GPU failed.
I really though that anyone going to these lengths wouldn't be bothering to do this to scam on amazon and would instead be gainfully employed??? What the hell.
I guess I can't buy anything on amazon anymore. Oh well.
If it says X model on the label, and OS also reports it as X it becomes tough to make a case for returns.
