It's compareable to a GF2-GTS 3D Speed wise, a G400 image quality wise, it can bring DVD playback below 10% CPU usage on a 550, and it can manage TV-output quality nearly as good as a Hollywood plus. And it has TV-in features.
So I guess it's a GF2 GTS with a TV-Tuner, a Hollywood plus and 2D that doesn't suck?
