I'm thinking about building a new media centre. I cant decide between the atom 330 or one of the new core i3's. would the atom be ok for 720p video.
The Atom will only play 720p reliably if paired with a GPU that does most of the work (e.g. Ion or a plug-in Nvidia card).
Edit: Actually a 330 will probably handle it under Windows (Linux codecs still seem to be single-threaded), but I wouldn't be surprised if you could find files it would still struggle with.
