Mmm... as you are using gnome2 with metacity (i.e., a non-3D enabled 
desktop) I don't know what could you tweak to make it to run smoothly. 
Let's see what the X gurus have to say in this regard.

That's a normal value for TFT/LCD displays but very low for a CRT.

I bet yes, but I don't know ATI closed source driver enough to make any 
suggestion. By Googling around you can found some, though, but this is a 
"trial/error" try-out:

Under "Modules" section:

Load "GLcore"
Load "glx"
Load "dri"

Under "Device" section:

Option "AccelMethod" "EXA"
Option "AccelDFS" "on"
Option "EXAVSync" "yes"
