        Time to execute Photoshop 7 test script while iTunes visuals are running full screen in the background. All times in seconds, shorter bars are better.

        The above test is a seriously difficult task for any processor to run. If you wish to duplicate it, this is what is involved. I would use caution - this CAN AND WILL overheat processors.

        If you have problems with your machine locking up while running this test, investigate the thermal bond between the heatsink and processor - this will stress your computer more than anything!

        • Set your monitor's resolution to 1280x1024, millions of colors.
        • Open iTunes and play a song. For this test I chose a 10 minute live version of a Rolling Stones track, and had it repeat in a loop so all of the processors tested in this series would be having the same visual patterns displayed.
        • Some of the iTunes visuals differ in CPU load, and this levels the playing field, so to speak.
        • Expand the iTunes window to fill the screen
        • Activate the visual effects, at full screen resolution.
        • Open Photoshop
        • Select the action script to run, and start the stopwatch.
