The Sony W800B is a really good TV for gamers. Its only major flaw is the loss of color saturation when viewed at an angle.
It also performs well in a bright room and can get bright, but some TVs like the Samsung H7150 can get a bit brighter. Unless you have a veranda, though, the Sony W800B can get bright enough.
Unfortunately, the smart TV features are not very good. They do the job, but they are slow. Check out our review of Sony's 2014 Smart TV platform.
