I think the real problem is the networking, not the streaming. Any core 2 duo processor should be able to stream with just the integrated CPU'S IGP. 3rd or 4th gen C2D should do just fine. I am not a fan of getting the lowest rated equipment possible for streaming. Maybe a cheap Pentium or low-end celeron will work and maybe it will not. Feel free to get a bay trail Atom CPU board and try it. Its only money. I prefer an i3 myself. I have on streaming PC with a 2500K and one with a Haswell i3 4430. Both work fine.
