Is 3gb enough for 1440p for the next few years? games are getting more demanding with every release, and I mean the witcher 3 looks incredible. i am gaming at 1080p currently, and everything i throw at it with 780ti sli obv works like a charm, but eventually i want to hit 1440p. would 3gb suffice, or should I wait til high end maxwell is released and see how it does with higher resolution?
