In this series of benchmarks we’ll be running the Half-Life 2 stress test with no Anti-Aliasing or Anisotropic Filtering enabled, with all game details on high.

The ATI Radeon X800XT Platinum Edition reigns supreme in our first series of Stress Test benchmarks. At all resolutions, the card is able to stay around 25 FPS faster than the NVIDIA GeForce 6800 Ultra. The same is true with the ATI Radeon X800 Pro and the NVIDIA GeForce 6800 GT, with the X800 Pro able to run 10-15 FPS faster than the GeForce 6800 GT.

Also from these tests we see that the ATI Radeon 9800XT outperforms the NVIDIA GeForce FX 5950 Ultra by around 7 FPS at each resolution.
