So, when I said re-examine the situation I meant that the tests should be rerun now that we have a board with much more memory bandwidth than we did before, the i850. The increased memory bandwidth might actually make it possible to see a difference in the AGP2x vs. AGP4x argument. The problem with AGP is that for vertices PCI is well enough, so adding more bandwidth wont boost the performance significantly, but for texturing it's way too slow so it wont be used for that.

Still, I wonder if faster PCI wouldn t be a better solution since that speeds up more then video.
Life is complex.
It has real and imaginary parts. Yes but it is conceivable that the number of vertices could grow to the point where AGP is required. Still, I wonder if faster PCI wouldn t be a better solution since that speeds up more then video. PCI-X and Infiniband are emerging standards for interconnects. One thing to keep in mind with PCI is that it shares its bandwidth with other devices, so video performance could be worse.
