I just managed to secure a XC3 + mobo bundle on newegg. I'm currently in the queue for the 3080 FTW3, but I am at 9/18 1pm, so I bought the XC3 due to uncertainty of availability. I was told that EVGA allows you to step up from the 3080 XC3 to the 3080 FTW3. How does this work? Once my spot in the queue is called for the FTW3, I can "step up" and just pay the difference? Or is the step up program something else entirely and completely disregards the queue system?
