Jack Ryan, I know the question is for Geren, but let me just add that I was at the Alabang Town Center last Sunday and Accent Micro and another PC shop confirmed that "only the 8400GS" can be used with the X3200...however, they advised me not to, since they claimed, "It's better to wait for another one with a low profile adaptor, since it might not be able to carry thru World At War", and they added that I should let Acer Phil in SM Mega to do the upgrade "Bec. I might loose the warranty"
Hope this helps.
