Well, multiple developers have pointed to the unified memory on the new consoles (8GB). Thus the idea of buying a new card, today, with <4gb seems insane to me. Can't you just imagine every PS4/XB1 port may have the same issues as watch dogs? Couple that with more people running 2560x1400 etc sucking down VRAM. I hope the GTX 870/880 etc for desktops sets 4GB as the standard.
