I'd think that the more memory your system has available for audio data, 
the less it will depend on your fixed storage (spinning or SSD).

Heavyweight desktop environments like KDE4 and Gnome 3 use a lot more 
memory for themselves, leaving less available for anything else.

And, sorry, had to laugh. When you mentioned "older laptops", my mind 
went back to my older laptop (the one just before this present i7 
system). A 32-bit 2.8GHz Celeron processor and 2 GB of RAM, without any 
of these modern accelerated GPUs driving the video. KDE4 crawled on it. 
And that was with a 7200RPM hard drive in it.
