Update @ 9:45pm: I heard that some AMD users were notified about their R9 purchase as well, calling it simply "R9". Since I didn't see concrete proof, I omit it from the post in case it was a hoax (as the story is still developing). I have since been notified of a tweet with an email screenshot.
Original post below:
Apparently, Newegg is informing customers that NVIDIA has settled a class action lawsuit with customers of the GeForce GTX 960 and GTX 980 cards, along with the GTX 970. It's currently unclear whether this is an error, or whether this is one of the sibling class action lawsuits that were apparently bundled together with the GTX 970 one. Users on the NVIDIA Reddit are claiming that it has to do with DirectX 12 feature level support, although that seems like knee-jerk confirmation bias to me.
Regardless, if you purchased a GeForce 900-series graphics card from Newegg, maybe even including the 980 Ti, then you should check your email. You might have a settlement en-route.
That's all we know at this point, though. Thanks to our readers for pointing this out.
