holy crap, you really do have that much upload! With that you can stream high def at 60 fps without breaking a sweat! But is not recommended because then many viewers that have less than 10MB of downstream will not be able to watch your stream. I think that with 2-3MB is more than enough.
Use Xsplit (because that's the only one I know) if not then just try to pur the bit-rate for sound ad video on the one you're using:
for sound use "128 stereo" if you want really high quality audio but more than that is just a waste of bandwidth because very few people have expensive Bose kind of speakers that could reproduce the quality anyway.
And for video bit-rate at least 1500 to 2000 with (h, x, whatever letter you see here).264 encoding.
This is a total of 2.2MBps which is reasonable but if you want to go elite then keep upping the video bit-rate as much as you want since you have 11MB of upload anyway but this will only put more unnecessary stress on the hardware. Now the final issue is the frame-rate... If you're gonna stream and play from the same computer then 60 frames would be too stressful even for the strongest CPU on the market and you're gonna make the Xsplit to crash constantly, so no more than 30 frames. If you'll stream from console or outside computer then do 60 frames and the stream will run much better.
If this doesn't work then I have no idea what to tell you because it's that simple.
