Using CAPS is very bad manners online. It is equivalent to shouting, which is what abbadon was referring too! But you corrected that in your second post
The HD4250 is very weak. You will probably want to buy a discrete graphics card. Which one will depend on the usual considerations - what do you play, what resolution etc.
For a FX4100, you probably wouldn't want anything more than a HD7850 or equivalent NVidia card for graphically intensive FPS games. If you are playing more strategy games then maybe a HD6670 would be enough. It depends.
