NVIDIA is using its Facebook page at http://www.facebook.com/NVIDIAGeForce to tease another upcoming graphics cards with the following image and the subtitle of "It’s Coming."
While there are zero details and the photo is about as ambiguous as it gets, we have several speculations about it. It could be another Kepler-based graphics card like the GTX 670 or GTX 660 but more likely, we are seeing something higher end that NVIDIA wants us to get excited about. Is NVIDIA already prepping the dual-GPU variant we are guessing as the GTX 690?
Like I said, it’s basically impossible to tell based on the photo, but apparently we’ll know "soon".
