your graphic card seems to be really old and cant perform the tasks as the new graphic cards can thus your low score..
there is some really great cards out now that can bring that card up to the 10 thousands and youll see a great inprovment in your gaming too!
look into the 6800GT or the ATI Radeon X800 Pro really great cards for their price
i did try and play cs and the graphics were terrible. i tried to turn on opengl but it said it wouldn't support it even though i remember having opengl on about a year ago when i used to play heavily. it also wouldn't support the higher (32bit) graphics option.
