From the Windows desktop, press "Start", then select "Run", then type in "DXDIAG" in the run dialog panel and press the "OK" button.
After a bit, DXDIAG will pop up and you will have to wait for the progress indicator in the lower left hand corner to disappear.
When the progress indicator disappears, select the "Display" tab from the tabs across the top of the DXDAIG utility. In the upper left quadrant (labeled "Device") of the display panel will be a "Name". This "Name" contains the description of the video card in your computer. That is what I need.
