Quick question ... about video cards..

Ok listen.. I know this is notebook. but i got such a prompt answer last time.. i posted here again

my desktop is running a Nvidia 9600 GTS, Has a 3,4 ghz P4, 1 gig of ram.....

i turn my shadows, and texture down to low quality and im running around CSS with 50 fps.. TOPS!!! :(, Anything i could be overlooking?

 

ALSO what should i overclock it to using Ntune..i have a extra fan if needed but as it sits my pc is blowing COLD air out the back.. so.,.
