Streaming benefits from more cores and higher clock speeds... Hence I would suggest the FX8350...
There are number of reviews and benchmarks available over the internet for both the processors... Those might give you some more idea...
Clock speed does not need to imply performance. What matters is how many operations per second the core can perform. A oore with lower clock speed can beat a core with a high clock speed, as we are observing within the batter among the current generations of Intel vs AMD CPUs.
Also, benefiting from extra cores can simply mean "being able to catch up with much faster Intel cores".
