3DMark06 simulates DirectX 9.0c (Shader 3.0) games and it also puts HDR (High Dynamic Range) into the equation to calculate its final score. So it simulates the most high-end games available today. Since we were comparing high-end cards, we ran this program in higher resolutions, as performance difference between high-end video cards is more expressive on such resolutions. We chose three resolutions, 1600x1200, 1920x1440 and 2048x1536. The results you check below. All video cards listed below were running with the default clock rates defined by the chip manufacturer.
