Well, I went with the GTX 970 because the price vs performance wasn't worth it. Would it be worth spending $650 for a 980 ti vs buying a second 970 for $350 to pair with what I have now? Or maybe I'll just wait a few years, putting my money aside. What would 2k buy me in a couple of years, compared to what I have now? I think this is a wait and see moment, considering that VR has a real chance of booming right now.
