Some cards that come with 256MBs of memory come with slower memory.
200mhz (200 DDR= 400) vs. 300mhz(300 DDR=600)
That is why some 256MB cards only cost a little more then the 128MB ones
Regular ATI 9600s (and PROs and XTs) have 128 bit wide memory pathways.
ATI 9600SE have only 64 bit wide memory pathways.

Now having even the slower 200mhz (400) memory is still better then the
graphics card
having to use main memory thru the AGP aperture.

Someone doing video editing might benefit from the extra memory on the card.
Also having the extra memory may just be a selling gimmick.

What are the advantages of having a 256 Meg video card compared to
having a 128 Meg video card?
I don't think their are any programs that require a 256 Meg graphics
card.
