Halo: Combat Evolved
The speed of Halo mostly depends on the pixel shader performance of the graphics card. This time the PowerColor X700 PRO can’t catch up with the GeForce 6600 GT just because of the great difference in their core frequencies. The RADEON X700 XT is also slower than the GeForce, but it still doesn't fall too far behind. This means you can achieve good frame rate in this game by overclocking the PowerColor X700 PRO.
The PowerColor X700 PRO (like the X700 XT as well) is behind the GeForce 6600 GT, but the RADEONs anyway prove very fast in this game – even the highest resolution, 1600x1200 pixels, provides comfortable gaming experience!
The PowerColor X700 PRO and the RADEON X700 XT are far behind the GeForce 6600 GT in 1024x768 resolution when FSAA is enabled, but get closer to it in 1280x1024. In the highest resolution the RADEONs are 10% and 20%, respectively, faster than the GeForce rival.
