Lost Circuits has published an article on the nVidia Quadro4 980 XGL video card

few weeks ago, we forayed into the realm of AGP8X to show the differences between the older AGP 2.0 standard and its replacement going by the suffix 3.0. Numerous changes in the protocol along with the move to octal data rate were supposed to yield some performance improvement, alas, as we showed, at least in gaming applications we were unable to eve document a performance increase from AGP2X to AGP4X.

At the same time, we did notice quite some differences in professional graphics applications running under OpenGL. It appeared, though as if we were running into some limitations of the graphics adapter in that the ASUS V9280 was seemingly unable to capitalize more on the increased bandwidth provided by AGP8X. Our rationale was that a more powerful adapter might be more suitable to show off the benefits of 2GB/sec AGP bandwidth and so we grabbed an nVidia Quadro4 980 XGL. It is hard to imagine missing the target of our expectations by a wider margin but ...... on second thought, there are lessons to be learned from our results...
