Just to reiterate and/or clear up any confusion that I may have inadvertently stirred up with this post - here's my story:
I bought a 1070 Founders Edition back in June. Nearly at the end of my window, I opened my Step-Up request to get the 1080 ACX model.
Fast-forward to me noticing the "Free PowerLink" offer that eVGA put up. I clicked the link, filled out the form with my current 1070FE as my "eligible" card and then submitted..but then wondered if I'd made a mistake in doing so. Therefore, I strolled over here to the Step-Up forum to post the question that started this thread -- the last thing that I want is for the PowerLink request to snarl up my Step-Up request! :)
EVGATech_ChrisB assured me that we'd work out my request for the PowerLink (which I definitely trust in).
I hope that this helps and sorry if I've muddied the waters for anyone!
