its quite simple, the cpu bottlenecks the gpu when the card can render the image faster then the cpu can provide data that is necessaryfor the game (AI/physics etc) to advance. Just think of a massive explosion with hundersts of parts, but the parts have a rather simple form and only plain textures.
The gpu could render this scene with several 100fps but the cpu can only provide the location of all that parts 10times a second (aka 10fps), so your framerate would be 10fps, regardless of what the gfx card can do .
