X-bit在這裡有非常詳細的測試,6600GT在
A)First Person 3D Shooters:
1)Call of Duty,
2)Doom III,
3)Unreal Tournament 2004,
4)Halo: Combat Evolved,
5)Far Cry,
6)Painkiller,
7)Counter Strike: Source Beta,

B)Third Person 3D Shooters <沒有測 AA/AF>
1)Splinter Cell: Pandora Tomorrow,
2)Prince of Persia: Sands of Time,
3)Hitman: Contracts,
4)Tomb Raider: Angel of Darkness
5)Thief: Deadly Shadows
6)Max Payne 2: The Fall of Max Payne

C)Simulators
1)IL-2 Sturmovik: Aces in the Sky
2)Lock On
3)Colin McRae Rally 04

D)Strategy games
1)Command & Conquer Generals: Zero Hour
2)Perimeter

這麼多遊戲的 4xAA/8xAF,1024x768,1280x1024,1600x1200 模式下(注意B大類遊戲沒有AA/AF數據)
比Radeon 9800XT好的有:
Doom III, UT2004, Halo, Painkiller, CS: SOURCE BETA,C&C General,
平手的有: Lock On, Colin McRae Rally 04
差的有 Call of Duty, Farcry, IL-2, Perimeter.
持平而言, 6600GT的 AA/AF仍然比 Radeon 9800XT好
我想以一張頻寬只有 128bit的中階卡...在 AA/AF有勝過9800XT的表現...已經算非常優異了吧
