Just wanted to chime in on my experience here so far. I bought my first 1080 FTW the day they came available and had a defective card. Called EVGA support as soon as I black screened and they Advanced RMA'd me a new one.
Received second card and experienced the black screen and fans at 100% plus the new added white scan lines. At the first sign of trouble I phoned in again and was told they were working on a fix, told to try debug mode, see if it helped and keep in contact.
Called back in today to give my report and was told there was a fix and would get another Advanced RMA.
I ran dual EVGA 970s for a while and was totally pleased with them. Now that I've dealt with EVGA support and two defective cards... I actually like the company more. I know spending hundreds of dollars hurts, when it feels like a waste, but EVGA support has been the single best customer support I've ever dealt with.
Hopefully this will resolve all of our issues, and we can all game happily ever after.
