In cases where the GPU is the bottleneck in a game having more Vram will not make a world of difference.

Notice in some examples the in game settings are not maxxed out or no AA at all so more Vram use is possible in some of them & even then using more forced driver settings could raise it some more but then the GPU may become the weaker of the equation unless you have a multi GPU setup.
