Performance

Far Cry

In 1024x768 resolution, without anti-aliasing or anisotropic filtering, the graphics card of the GeForce 6800 GT class easily handles the graphics load, so it is the CPU that becomes the bottleneck. That’s why the fps rate grows but slightly during overclocking.

The performance bonus is more easily felt in the other modes. Moreover, the value of the bonus suggests that the game speed depends on the GPU frequency rather than on the memory clock rate even with FSAA and AF enabled.

Doom 3

It’s similar with Doom 3: the performance growth is small in the easiest modes, as the central processor becomes the main bottleneck in the system. Doom 3 is overall more indifferent to overclocking than Far Cry: the graphics memory bandwidth must be important for this game, and the memory chips on our sample of the graphics card had worse overclockability than the GPU.
