LXDE runs way smoother than Gnome 2 in my experience.

On my old hardware, KDE is a resource hog.  The DE runs like it is
moving through molasses.  On newer hardware it probably isn't
noticeable.  And for the short time I did run it, it was different
enough that there was a learning curve.  LXDE and XFCE are probably
much closer to Gnome 2 in behavior.

I'm using the Gnome 3 fallback mode on F15, and my DE has snappy
response. I suspect the same would be true of LXDE or XFCE.
