Actually it's hard to figure out what flux and quality does. I have been monitoring my Twitch channel on a laptop computer while streaming, but it seemed to me that the flux gets interrupted all the time (but you told me that it's not).

I was broadcasting (via the nVidia Shadowplay panel) in medium quality, which is 480p and 30 ips, with a 2 Mbit/s upload.

I can probably run 720p and 30 ips (3.5 Mbit/s), I also have a "custom" setting, but I can't go over 720p anyway. I can allow up to 5 Mbit/s upload however. I might need to run some tests.

Unfortunately my girlfriend is also using the Internet on her computer, she obvioulsy needs to watch to some soap-opera while I'm playing, and she'll be very angry if she can't anymore. So I need to take that in consideration, too
