In my experience, there are diminishing returns as you keep adding RAM. On Windows and Linux computers, I don't notice much difference when going beyond 2GB. Is there a G4 that can take 4GB of RAM? I thought most of them were limited to 1.5GB, with a single model accepting up to 2GB. I'm not familiar with the MDD models, though. -- Rich On Nov 9, 2007 6:52 AM, <arricam at 295.ca> wrote: > How quick will 4 GB Ram, make for applications. > ie: Photoshop, FCP,etc.
