[Upgrading the video adapter]
The AGP (Accelerated Graphics Port) version of the ATI 3D Rage Pro Turbo graphics processor and 4MB of video RAM is integrated on the motherboard. The video RAM is physically soldered to the motherboard and cannot be upgraded. However, AGP technology makes use of system memory, decreasing the need for upgrading the video memory.
AGP technology improves system performance by providing a high speed pathway between the PC's graphics controller and system memory. This pathway enables the graphics controller to execute texture maps directly from system memory rather than caching them in its limited local memory. It also helps speed the flow of decoded video from the CPU to the graphics controller.
For more information on AGP, visit the following site:

If you decide to replace the existing video card, you will need to purchase a PCI video card. The motherboard does not have an AGP expansion slot (the existing video processor is integrated with motherboard's AGP bus). The SONY Internet Group Technical Response Center CC5Y
