Perfect for games, excellent for video editing, ok for 3D.
There is hardly any lag when pushing all the settings to the limits at 1080p resolution, even with anti-aliasing. Definitely a performer for games.
Does well when tested in video editing. With Adobe premiere, playback is smooth even with filters added. In Sony Vegas, frames get cached very quickly and makes editing a lot more fun.
The downside of using it in 3D applications is that the gtx 570 is not a supported card when using Maya's Shader 2.0 viewport rendering. There is also a noticeable struggle when too much ploygons fill the scene. As for GPU rendering it does very well, render results are fast.
Overall, great card!
Strengths: Perfect in regard to games. Handles what you throw at it.
Weaknesses: For 3D applications, preview rendering is not optimal enough.
