Performance in First Person 3D Shooters
CrossFire does provide certain benefits here, however, in pure mode it is not that significant at all, and doesn’t exceed 15-17%. Even in this case a single GeForce 7800 GT graphics card runs faster.
In eye candy mode, the situation is a little bit different: until 1600x1200 resolution CrossFire runs as fast as GeForce 6800 Ultra SLI, however, in 1600x1200 CrossFire suddenly dashes forward yielding only to GeForce 7800 GTX SLI. Compared with a single RADEON X850 graphics card we see a 35% performance improvement. It is not a dramatic increase, but among the SLI supporting platforms only pairs of two GeForce 7800 GT cards and two GeForce 7800 GTX cards appeared faster than CrossFire.
