Yeah, the reason Towelliee and the other big guys can run such good quality is because they're partners, so have quality (transcoding) options available and can stream at very high bitrates without shutting out viewers on slower connections and systems (if they buffer, they can just go to a lower quality and still watch). If you're not a partner, the max recommended bitrate is 2000, which is more than enough for a decent-to-good quality 720p@30fps stream.
Mitigate expectations and work within the technological constraints... there's a reason 720p@30fps@2000kbps is a well-known 'sweet spot' for non-partners, balancing quality with viewerbase accessibility.
Just remember. Few will come TO your stream just because you have crystal-clear 1080p video. But many will LEAVE your stream if they get stuck in buffering hell because you're running at a rate higher than their setup can download/process.
(edit) Oops. Didn't see there was a second page, was still responding to the first page content. New design has the multi-page bit blend in a little more than I'm used to.
