AGP Limits

I keep seeing many benchmarks in the forums and alot always seem to claim that there limited by the speed of a GFX card at high res.
I was wondering what would the real limit (FPS) to a AGP port be since its real physical design is 32/66.
X2 and X4 can work around this but mainly affects the gfx card not the AGP bus.

 
The AGP bus has an HUGE through-put, there isent 1 game out there that could satureate a 2x AGP slot. PCI slots used to hold back video cards but this is no longer a problem due to the fact that the AGP(Advanced Graphics Port) slot was invented for the sole purpose of video cards. Currently there in terms of FPS, there is no way the AGP slot could bottle-neck any current video card.
 
as graphics cards get faster and faster, there is less and less need for the AGP speed to increase. More data is put through the gpu, and stored in the video RAM, don't need the cpu or system RAM much anymore.

There is no definitive limit. In an ideal world everything would be transferred right on the card and we would have enough memory bandwidth straight on the graphcs card that we wouldnt even need anything close to AGP1X.
Modern cards rarely touch the AGP bus bandwidth as it is.
