While we got some leaked information on it on Tuesday, the ATI Radeon HD 4830 graphics card was officially announced yesterday and it provides consumers with a cheaper option that still carries great specs.
Features for the 4830 graphics card include many that are included in the higher-end models. They are simply cut back a bit here. For instance, there are 640 stream processors instead of 800. However, the 256-bit memory bus remains, as does full screen anti-aliasing and anisotropic filtering.
