I recently bought the HD 4830 1gb version from ATI. When it was fist installed it worked fine, however, recently I have been getting severe framerate drops in many of my games, Left for Dead being an example, with the fps dropping to 20-30 from 70-120 when a horde comes on screen. This also seems to happen in things like CSS and TF2 when there are alof of players on screen at once. Also in HL2 and episodes and Bioshock it happens in certain sections of the game, and when there is alot going on on screen.
Hope someone can help!
