XFX GTX 260 XXX SLI Performance

Quake 4 is a game built on the Doom 3 engine. Benchmarking was performed using Quake4Bench and a custom timedemo recording. The benchmark was set to run a total of 5 times, with Quake4Bench automatically calculating an average result at the end of the run.

Houston, we have a problem. Quake 4 turned the tables on the results. Rather than seeing ATI have the better scaling we see the GTX260 XXX take the advantage this time around. The ATI rig actually lost FPS in a dual card setup, something that should be addressed with driver updates but nonetheless the NVIDIA solution takes the Quake crown if you are looking for dual cards but in single card format, the HD 4870 shows the GTX260 XXX the door.
Race Driver: Grid is a visually taxing game that perhaps represents a challenge to any graphics system. The benchmark was run a total of 5 times using Fraps with the highest and lowest scores removed leaving  the remaining 3 runs to calculate the average fps.
Once more NVIDIA has the upper hand with regards to GRID. With no Crossfire profile available at the time of the review the ATI solution was blown out of the water in a dual card setup in comparison to the NVIDIA rig. In single card format the results were almost identical so one can only hope that ATI can solve the Crossfire problem with this game.
