Streaming pc setup

so the first thing i need is a capture card i was guessing the aver media would be the best option 

the second thing i need is fans 120mm cause mine are really loud right now and im sure that will get annoying 

so here are my streaming pc (secondary pc) specs it has a h61m motherboard and a Pentium the one at 3.0 ghz and its ivy bridge 500w psu so i need a hard drive and ram 

i really would like streaming to be a carrer for me so i would like the best possible setup for all of this and another question will i be able to have 144hz with the aver media setup from another computer 

We need you to answer are the ones i do ??? on

Motherboard = ok

CPU = 3ghz 2core very dated

What kind of streaming? twitch stream? Nvidia shield stream? media center stream? O,o
