Simply put the pci express bus is capable of pushing more data than any video card around. That's gonna change soon enough but they are already working in pci e 3.0.
very true... even an HD4870X2 would be hard pressed to saturate a x16 1.1 slot... with a decent OC you might find it kinda falls down in high resolutions, but up to 16x12 it'll be fine... the HD5800 series and the GTX 300 series will change that tho... but a 2.0 slot will be fine to support any of those
3.0 wont be really necessary until early 2010 at least... but by then it should be very common
