"The Catalyst 10.3 drivers are really weird this month. What tends to happen is that we'll get the driver a few days before it goes up live on the ATI website. Once it goes live then we release our performance analysis comparing the latest version to the previous one.
This time around, though, it seems that ATI have ants in the pants and can't keep still because they chose to release a preview driver of the 10.3s which is essentially the driver you're going to see, except it’s non-WHQL. In saying that, the WHQL driver will miss Eyefinity 6 updates and an Alien vs. Predator optimization. We're sure the 10.4s will include those updates, though."
