Note that if you've got a 64 Meg memory video card, and X uses 4 megs of
system ram, it will show, in linux, as using 68 Megs of ram. Turning off
X, however, will only free up the 4 megs of system ram, not the 64 on the
video card. so, it's not uncommon for folks to see a modern video card in
their system, look at top, and go "geeze, X is a total memory hog" when in
fact it's just that linux / top count the video memory as part of the
memory allocated to X.
That said, I'd at least run a less heavyweight window manager like
afterstep or twm, not gnome or kde on a box like that one.

Also, look at si/so (swap in and out) to monitor swap activity. If those
numbers are low, then swapping isn't an issue...
