Never had a problem until something went wrong. I work in IT support and have done for the last 10 years. I ran all checks and provided the store with the links where AMD admitted to the issue with no resolution as of yet for the 5700 GPU and advised the store that the card would show no faults this is a software/driver issue on AMDs side.
I wanted to check the process as I handed the card in to be tested even though as I had told them the card was functioning and would show no fault if tested, so I called up to be spoken to in an abrupt and very rude manner on the phone, so then went back in as didnt appreciate the way I had been spoken to, the same person came out to talk and yelled at me! Then told us that he doesn't care what the ACCC says as their rules superceded this and if they can't find a fault we'd be charged $50 and couldn't give a refund as what are they going to do with a faulty card!
Only by sending a ACCC complaint letter did I get action and a full refund. If this had gone differently I would of spent the extra money in store to exchange for a 2070 super, instead now I am going elsewhere to buy and advising all my IT contacts not to shop here.

Approximate cost: $759
