Depends on the game, a lot of the ones on that list are already dated.
Wow Battlefield 4 is already dated? I must be getting old and losing my head. Seriously, no vram brick wall on any of those charts. Even the 2 gig per gpu vram GTX690 is hanging in there at ultra hd. Unless there was stuttering and fps drops that the reviewer isn't reporting? I guess minimums would help indicate running out of vram....
