I'm working on a slideshow on my dad's Core 2 Duo 2.4Ghz Mac Mini, and it's PAINFULLY slow. There's a noticeable several second wait when changing settings for a photo (like how long it is) and often times when playing, it gets "stuck" on a transition or photo, and the preview window doesn't change. My dad has 2GB of RAM and I have 3GB of RAM. My Core 2 Duo 2.4Ghz MacBook Pro is a tad faster, but not much so. So I'm trying to figure out how to speed this up, as the whole process is taking way too long. These extra few seconds here and there really add up when working on a long slideshow. I think our computer processors and graphics processors themselves are powerful enough so it's probably something else. What would speed up iMovie more, an SSD, or maybe 6-8GB of RAM?
