It depends largely on game title and settings. For example, on Witcher 3, even the Titan or 980 TI can't maintain even 60FPS at 1080p 60hz with some of the gameworks features turned on. The 970 might be able to maintain the performance necessary for a good gaming experience on a 144hz monitor if you're willing to turn down some features. On other titles, it might require a drastic reduction in quality settings. My advice is to NOT go with a 144hz monitor unless you're buying a R9 295x2, GTX 980, 980 TI or Titan X, but that doesn't mean you can't still have a good gaming experience with a 144hz monitor and a lesser card if that's the way you choose to go. You'll just probably have to reduce some settings. If you don't mind doing that, then it might be a good fit.
