Not sure if it requires a "qualified graphics card" but i get an error message about hardware requirement when attempting to use the code, i've read through the image attached to your message and it seems only systems with GeForce 1080 or 1080Ti installed are qualified to redeem the code... So... Unless i've missed something, good luck to the next person with 1080/Ti card to claim the code My meager 980Ti strix doesnt pass as it seems!
Sorry, my bad
I didn't realize key was for only GTX 1080 or GTX 1080Ti card,.. guess it figures as I got two keys when I bought my cards,..
I was worried about stacking multi cards, and not having the inlet/outlet line up,.. with single card your going to be fine.
I have three NIB FE Phanteks Glacier Series blocks, I'm thinking about selling if your interested. I bought them last month to add third card and chiller,.. but still haven't been able to buy third FE card, newegg seems to not be restocking 1080Ti cards,.. been out of stock or they are sold be others not excepting bitcoin for crazy high price.
