Benchmark scores in this review are not comparable to any other review.
  • We used the same Windows installation on all systems and moved the HDD between test rigs.
  • All games were set to their highest quality setting unless indicated otherwise.
  • AA and AF are applied via in-game settings, not via the driver's control panel.
Each benchmark was tested at the following settings and resolution:
  • 1024 x 768, No Anti-aliasing. This is a standard resolution without demanding display settings.
  • 1280 x 1024, 2x Anti-aliasing. 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. Most common widescreen resolution on larger displays (19" - 22"). Very good looking driver graphics settings.
  • 1920 x 1200, 4x Anti-aliasing. Typical widescreen resolution for large displays (22" - 26"). Very good looking driver graphics settings.
  • 2560 x 1600, 4x Anti-aliasing. Highest possible resolution for commonly available displays (30"). Very good looking driver graphics settings.
