Smooth to me can be less than 60fps; the main thing is that there shouldn't be stutter/jerkiness or big fluctuations in frame rate. If need be, I always turn down or give up AA in order to keep settings dialed in at High/Very High/Ultra or whatever the game offers but I'll be honest; my backlog is huge so I tend to run a year or two behind on games and so far, I haven't had any issues with performance. I have SLI 980s now but I can say with certainty that one 980 did very well in anything I played. I've recently been playing Alien: Isolation, Batman: Arkham City, and GTA V so take that for what it's worth. Exactly. This is all I was trying to say, except rather than focus on benchmarks and frame rate numbers I just play the game and decide for myself if it feels fluid. If it feels like it's bogging down then I reduce settings, but I very rarely have to do that because A) like I said, my backlog tends to keep me from playing most things Day One, with GTA V being an exception and B) I don't care about maxxing AA in every title as the performance hit usually isn't worth the improvement at high resolutions like 4K (IMO). It's one of the easiest things to turn down or off and still have the game look great with max textures, draw distance, etc. etc.
