Question / Help Awfully laggy stream.

[HungarianMyspaceUser]

So I tried streaming,but when I would enter a game the stream would get quite choppy, so I decided to lower the bitrate too 1000 and I had brought the resolution down to 720, I believe that I should be able to run it at that current setting so im reluctant to bring it down. It should be worth noting I live quite far away from the other servers, so I checked the twitch bandwidth test and the closest server had around 4500 kbps.
I have a gtx 960 with a i5 4690k.
Here are the logs for the stream, and I do apologise if I left anything out.

Thanks for all the help, guys!
