Meh, you can try, but don't expect nice results. Maybe the AMD gaming app's DVR system is your best bet, as your cpu is barely powerful enough for recording, let alone streaming...
The app however, instead of using the cpu, leverages the gpu for a performance hit of around 5 to 10 fps, depending from game to game, while letting you run video recordings, highlight recording and direct twitch streaming (pretty much works the same way as Nvidia's shadowplay)
