Memory is the biggest thing here.
4GB is the suggested minimum amount of RAM to run darktable (see the
manual: http://www.darktable.org/usermanual/ch07.html.php).  If you
run other things (like, say, a browser with many tabs) on the system,
the more the better.  Of course, you can counter that with sufficient
amount of swap, but you have to be prepared for that being used ;-)
For more than 4GB, I'd definitely start using a 64-bit kernel.

Also, GPU memory needs to be 1GB or more for darktable to take
advantage of the GPU (ref: the manual: 
http://www.darktable.org/usermanual/ch07s02s03.html.php)

Cheers,
Richard
