Are you running many memory hungry applications at the same time, like 
kde, firefox, thunderbird, gimp, etc. If you're running out of RAM and 
your machine is swapping, things can get pretty slow. You can see swap 
statistics by running 'swapctl -lk'

Other than that, maybe there are issues with display driver, or something
