As for graphics, the laptop supports six nVidia GeForce modules, each with 1GB of RAM. The difference is with connectivity, as the base card relies on VGA, but the higher-end models add Dual-Link DVI, HDMI, and Open GL3.2. Internet is another optional accessory, as the base only comes with a 56K modem, though options for Gigabit LAN, WiFi, and WLAN are all available at a either premium. Everything else is including with the base—a Kensington lock slot, a multi-card reader, and one ExpressCard slot.
