Test System

• All video card results were obtained on this exact system with the exact same configuration.
• All games were set to their highest quality setting

Each benchmark was tested at the following settings and resolution:

• 1024 x 768, No Anti-aliasing, No anisotropic filtering. This is a standard resolution without demanding display settings.
• 1280 x 1024, 2x Anti-aliasing, 8x anisotropic filtering. Common resolution for most smaller flatscreens today (17" - 19"). A bit of eye candy turned on in the drivers.
• 1680 x 1050, 4x Anti-aliasing, 16x anisotropic filter. Most common widescreen resolution on larger displays (19" - 22"). Very good looking driver graphics settings.
• 1920 x 1200, 4x Anti-aliasing, 16x anisotropic filter. Typical widescreen resolution for large displays (22" - 26"). Very good looking driver graphics settings.

In order to get scores for single-GPU HD 4870 X2, I disabled one device in Windows Device Manager. These scores are interesting because they show how a 1024 MB GDDR5 HD 4870 would perform. The normal HD 4870 has only 512 MB of GDDR5.
