I have a 512MB Video Card, ATI Radeon X1600 to be accurate, and 1GB DDR400 of RAM. The AGP Aperture is the allocated size of "Emergency" RAM that would only be needed if I ever run out of memory in my Video Card, for what I understand. Since I have a 512MB Video Card: 1. Should I even worry about this setting? 2. Should I lower it down to 32MB, to make sure I have more non-allocated RAM for other use?
