I actually don't attribute the timing to lagging memory or processor power in my case. Its not quite as accurate as it is on PS3 or Xbox 360 though. I figured it is just the game moreso than the processing speed. Kind of like on the platform games where you can correct for the lag if you have a HD tv who's picture is slower than the game speed (in Rock Band anyways).
My GF's wing does the same thing.
It is a PPC afterall. On some songs more than others and sometimes only in a certain section of the song. The notes just don't match perfectly as it should in theory, but still definately playable.
