Far Cry

The CrossFire platforms both reach easily the maximum possible speed on this level and have almost the same speed thereafter, indicating insufficient texture fetch speed or insufficiently high memory bandwidth.

This is not a big problem here, though. You can play in any of the standard resolutions with turned-on 14x Super AA on the Radeon X1800 or X1900 CrossFire. The GeForce 7800 GTX SLI doesn’t permit this.

The advantages of the newer graphics subsystem from ATI are more prominently outlined on the Research map, especially in high resolutions. Yet even here, with more complex shaders to be executed, the performance gain is too small to justify an upgrade of your current Radeon X1800 XT CrossFire configuration.

Note that if you don’t plan to use Super AA, it may be more profitable for you to purchase a single Radeon X1900 XTX than two Radeon X1800 XT for a multi-GPU config. These two solutions differ but little in their performance, but a single Radeon X1900 XTX costs much less and doesn’t require a CrossFire-compatible mainboard and also consumes less power.
