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.
Across the board we see the cards struggle with AA and AF. Street Fighter IV is of course an exception and we're seeing an average above 60 FPS here which is great. We can also see the new driver really boosted performance in it and Mafia 2.
As for performance against the ATI offerings, the GTS 450 Super OC has no problems dealing with the HD 5750; it's a little tougher fight against the HD 5770 and we see it win some, and lose some.
