free -m shows 2GB used but gnome-system-monitor shows 1GB

free -m shows
             total       used       free     shared    buffers     cached
Mem:          2007       1947         60          0        446        449
-/+ buffers/cache:       1051        955
Swap:         3153          2       3151
But gnome-system-monitor shows 1.0GB (53.2%) of 2.0 GB used.
How come the difference ?

(The SWAP details are same)

The disk buffers/cache are really free memory that is being used for disk cache, 1051 megs there. any programs that need it can get it, but right now it's disk cache. It just depends on the way the program decides say what is free memory.
