Any benefits to iMovie, iDVD, and iPhoto?

[PieMac]

Would any of these applications benefit significantly from a dual 1.25 PowerMac vs a single 1.25 PowerMac?

I know that FCP and Photoshop are geared for a dual processor setup...just curious about the OSX apps.

Also, would any benefit derive from the DVD burning process itself?

I like iPhoto, though its annoying that it can not handle th elittle 30sec movie clips I take with my Olympus, leaving me to still open the disc manually and find a place to put them.... anyone have any info/suggestions on this?

but yes, they all would run much faster than a single G4, especially FCP & Photoshop
