I don't know if they were or not. My techie knowledge in this regard is limited. I do know that I have had some issues with my system for the last week but that might be related to Shadowplay. I am not sure yet. I'm being careful with it because I want it to last another 8-12 months so I can upgrade specifically for SC.
Well mine was - its run a 4.8 OC stably on air since launch which is pretty damn good. Problem is that crappy Southbridge has caused me problems and I've gone through a lot of drives. Still was worth it for that peach of a stable OC.
