Not to mention the built-in advantage of Intel's much better supported QuickSync video encode/decode if you're doing any sort of media streaming.
Won't matter if your main computer does the decoding, and for the price of one good computer that can stream to all devices including crappy ones versus all good ones and a cheap NAS to host, which would you choose?
Guess the question then becomes, do you need transcoding on the device streaming?
If it only costs you $100 to upgrade all your non-server devices from crappy to good, you have to tell me where you shop.
