So there's a whole lot of texture data that needs to be transfered to the memory for a complex 3D-scene.
And where are they loaded from ?
HD, CDROM ?
The best hard drives (SCSI Ultra 320 15000 RP) hardly support 80 MB/s. AGP * 1 is 256 MB/s.
Texture may be compressed so you could eventualy get higher speed than your CD/HD. Still 256 MB offers a good margin.
