The higher the cost of the Item, the greater the attention Amazon will generate toward the refund/replacement.

By no means Is It Impossible to SE, nor Is It an arduous task If you've formulated your SE accordingly. I've known users who've simply used the wrong Item received method, sent their old GPU and received a replacement. It's not possible to be definitive with the number of reps you'll deal with. Every SE Is based on It's merit, so best to take It as It comes.

Thanks for the advice .
