i found this while searching intel GPUs- http://www.mac-forums.com/forums/showthread.php?t=91514 the second post in that thread says something about apple limiting the amount of RAM the X3100 can use to 144MB. why would they do that? is it just the poor drivers they use, or did apple do this on purpose for some reason? is that why the X3100 in windows is so much better? i realize that thread could be bogus but it was bothering me so i decided to ask MR!
