So 9 months ago i did a step up on my 2080 to a 2080ti. I uploaded my invoice from the original 2080, paid the diff, etc etc, got my 2080ti. However it just died and so i have to go through the RMA process, and its telling me to upload the invoice. Since it was from a step-up, my assumption is EVGA should just KNOW this info since they were the ones who processed it. ive got all the emails from the 5 steps of the step-up process, and the email when it auto-registered my step-up card....anyone know what i should attach as the invoice form?
