"Had trouble with my GTX 970 ftw+ (bought along with 10 year extra warranty for €32,- euro, also registered on their website).
It was always crashing within 15 minutes on certain games, until i found out that underclocking the card solved the issue with those games.
Heared from a friend that EVGA offers advanced RMA and decided to make use of this since they will send the replacement GPU in advance after paying a deposit.
Asked EVGA in my RMA request wether it was possible to upgrade against payment to the 1070 series, unfortunately this was not possible but i wasn't surprised at all that they wouldn't do that since that service is only available within 90 days of purchase.
When i received the replacement and opened the box, i was surprised to see that it was not the GPU in question, but infact it was the newer GTX 980 TI SC+!
After sending back the GTX 970 ftw+ i got my deposit back within a couple of days.
The customer service was fast with responding and very kind/helpful, my next card will definately be another EVGA!"
