Virtual is how much it thinks it has access to, not necessarily how
much it's actually got holding bits. I usually go by the "resident"
column.  Xorg is a special beast because it's got so many processes
running under it. Its CPU usage also looks high, but when I've asked X
type people about that before, they said it means some graphical
application is spamming X with requests and X is trying to keep up
with them, so I'd actually look at seeing what happens with killing
individual applications and which makes a big difference to X's
resource usage.
