That being what the cost of a whole new game, for some, this makes the world of difference. GTA V A memory-hungry game to the fullest; where the more vRAM, the better. That is, the 970's 3.5 GB is just about the bare minimum, to run this game at max, 60 FPS. The 960's 4 GB are not fully taken advantage of on the lower GM206 Maxwell architecture. Therefore any additional vRAM here would be best for a more constant frame rate, with less dips and stutters between lowest and highest framerate.
