Taiwanese manufacturer MSI has now introduced Afterburner, a graphics card utility based on the popular RivaTuner. Free for download, use and abuse, the application enables users to adjust GPU, shader and memory frequencies, the fan speed, and, for those with a Lightning series card, even voltage tweaking is available.

Afterburner also includes a hardware monitor, profiles, and customizable skin support. To give the software a try see this page for the required download.
