The Sapphire Toxic X1900 XTX is still unable to break away from the standard Radeon X1900 XTX. The limiting influence of the CPU is felt strongly in low resolutions, but the two mentioned cards are in the lead in 1600x1200, stopping very short of the 100fps mark.
The GeForce 7900 GTX equals the Radeon X1900 XTX and Sapphire Toxic X1900 XTX in 1024x768, but the Radeons take the lead as soon as 1280x1024. In 1600x1200 Nvidia’s flagship product is even slower than the humble Radeon X1900 XT. As for the picture in general, Far Cry is not a hard application for modern graphics hardware even if we talk about high resolutions with FSAA.
Despite the poor implementation of HDR support for Radeon X1000 cards, the Sapphire Toxic X1900 XTX yields 56fps in 1600x1200 and is only 10% worse than the GeForce 7900 GTX. This should be enough for comfortable play, but we’d suggest you limit yourself to 1280x1024 to avoid slowdowns in the heaviest game scenes.
The same is true for the Research map, but the performance is somewhat higher since the action goes on indoors.
