I have an ASUS board with the nvidia 6150 chipset and an athlon fx-55
(single core). With three 512mb sticks in it (long story, one module
died, bought two more, waiting on 4th rma, blah blah) the video and
audio were choppy, the frontend was slow.. generally unhappy. I
removed the 3rd stick and everything went back to normal. So at least
in my case, dual channel made a significant difference.
