I find the ALi chipset to be the best Super Socket 7 chipset I have worked with.
Setup is as easy as with other boards.
The manual is thorough. I have not experienced any AGP slot difficulties. I am running a Matrox G400 with all of the trimmings. I wonder if maybe these other video cards mentioned are just a little to greedy when it comes to power consumption. In advanced chip design you generally use less power, not more.
