Are any of you able to stream with 10 clients running with these setups... specifically the 3930K w/ 670/680 4GB or equivalent ATI?

Loading up XSplit on my current machine, which runs 5 no problem.. and it's game over. Instant 50% reduction in performance, 75% reduction or more when I start streaming.

I was wondering if similar performance hits happen 10 boxing even with much better hardware.

I've only seen one 10 boxer stream consistently without performance hits but this particular boxer is running server grade components, like 24-32 cpu cores, two 690s, etc.
