The PC is too weak for streaming. It weak for recording too. I think, 320x240 is the max resolution for this PC to encode facecam only videos.
I tested same config few times. It can run few games but streaming or recording it - no way. You need faster PC and dedicated video card, not APU. It shares memory and has low bandwidth, low frequency, it lacks hw encoding modules. This is net based machine. You can browse inet or play simple games, watch videos (up to FullHD, if player uses dxva accelerations). Youtube videos can run up to 480p without stutter in chrome (acceleration enabled). This is limit for this machine.
