I have a new Rev B. G5 w/ 2.5 GB of RAM, having just sold my Dual 1.42 GHz G4. Oddly enough one of the things I notice is sloppy iTunes playback.

At times some of my tracks stall, much like a cassette tape player would if a battery was running low. Also, I notice alot more pops in the mp3 files.
It's intermittent, thankfully but not something I'd expect from a G5 AT all.
I'm using the Harmon Kardon Soundsticks w/ USB.
This sound crazy? Any ideas why?
(I'm compressing my CDs using MP3 and not AAC, though I never had a problem w/ that before on my G4.)
Thoughts?
