This should work using a 4-port card. I use an Intel XL710 card with 4 10G ports. But, back to the external 10Gb switch question, I haven't used one, but it depends upon what streaming rates you need. If your streaming rates are slow enough, it may work for you. But, if you are trying to stream 8 ports simultaneously, you would be limited to 31.25MS/s since it would all be going over the same 10Gb link. And, the switch may add other issues.
