title: Lightweight X window manager/environment
body: <p>My machine is seriously underpowered, and I think I need to start conserving every spare cycle.  I know that my Gnome environment seems to underperform compared to my coworkers' KDE setups.  But if I'm going to make that big of a switch, I might as well consider running something even lighter.</p>
  
  <p>Is it possible to survive on a lightweight window manager and still run modern apps (Firefox, Eclipse, OpenOffice)?  What's a good candidate window manager for me to try, and what do I need to know?</p>
