yeah, pic isn't really supposed to be for vid. cards because 1. they're so old 2. they're so slow compared to what's out now. The agp ati 9250 will pwn that pci 9250. Of course, there's always pci express, which even faster than agp, but that's the new generation. Old is agp and old old is pci. Yeah, 2x as opposed to 4x/8x, and then pci ex. is 16x. Hope this helps.
Macbook Pro and Logitech z5500s. All you really need.
