High Quality AA and AF
Our high quality tests let us separate the men from the boys and the ladies from the girls. If the cards weren't struggling before they will start to now.
Mafia II, AVP and SF IV sees the HD 6850 and HD 5850 perform very close to each other. In all games we also see the new model win out against the GTX 460 OC.
Far Cry 2 paints an interesting picture. While it does fall a little behind the GTX 460 OC, its performance is significantly better than the HD 5850 and HD 5870. With 8x AA on we saw the AMD HD 5000 series really fall over under Far Cry 2. Clearly this has been tweaked.
