F.E.A.R.
F.E.A.R. is such a heavy application that the new chipset from ATI can shows its advantages here. The performance gain is never bigger than 3fps, though. Moreover, the results for the 8x and 14x Super AA modes are of a purely theoretical interest only, the min speed being below 25fps and the average speed not reaching to the required 60fps.
Half-Life 2
The CrossFire Xpress 3200 shows its very best in the high-resolution textures heavy Half-Life 2 . It is about 30% faster than the Radeon Xpress 200 CrossFire Edition in the 4x FSAA + 16x AF mode. The gap is 10-15% in the 8x Super AA mode and then vanishes completely at the higher antialiasing level because factors other than the PCI Express bandwidth begin to limit the system performance.
