Here is the answer. If you want to play 3D games or use 3D applications, upgrade to NVidia card and use NVidia proprietary driver. ATI drivers are very buggy and may crash X or whole system when running 3D game or application; sometimes ATI drivers do not crash but you can see missing textures or other artifacts in you 3D game/application. Some 3D games/applications may work fine with ATI driver but only if you are lucky.

If cursor is still moving, then your system probably didn't freeze. You can try Ctrl+Alt+Backspace first to restart X. If this does not help, try Alt+SysRq+K (SysRq key sometimes labeled as "Print" or "PrtScr" or "Print Screen" on a keyboard, and usually located near scroll-lock key). If the kernel still alive and you have SysRq keys enabled in it, it will kill your "frozen" X server.
