The following is an updated demonstration of the antialiasing (AA) quality offered by the GeForce 8 Series running in single and SLI configurations. Note that the comparison has been updated to include SLI AA, which was recently added as an option via an updated driver for the GeForce 8 Series.
The antialiasing modes offered by the GeForce 8 Series are demonstrated by using FSAA Tester from Tommti Systems. FSAA Tester has a variety of useful image quality tests such as rendering the image shown below in an 800x600 window. A set of the full-size original and enlarged (1.66x) images that are being used in this comparison can be downloaded here (~1.6 MB) and here (~2.2MB).

The following JavaScript applet shows the effectiveness of each antialiasing mode. Each image in the comparison was created by cutting the left mid-section from the corresponding full-size image and then enlarging it by a factor of 1.66.
Comparisons are accomplished by clicking on a labeled antialiasing mode located under the displayed image. This action will overlay the displayed image with the selected image (~90KB). The overlay process will execute much faster after all of the images have been saved in your browser's cache.
In addition to 8x multisampling antialiasing (MSAA), which is referred to as 8xQ, the GeForce 8 Series also features 8x, 16x, and 16xQ Coverage Sampling antialiasing (CSAA). In order for CSAA to function, antialiasing must be enabled within an application and is therefore appropriately labeled as "Enhance the application setting."
