that is a good idea!,

Also what i do is set my disk cache to 1024, and that from what they said on wikipedia. It said the disk cache will eat up that 1mb ram so video doesn't use it.

"David Pogue's book Macworld Macintosh Secrets observed that one could speed up video considerably if one set the disk cache size large enough to force the computer to draw video RAM from faster RAM installed in the SIMM banks."
