Do I need a video card for HD broadcast or will integrated graphics be enough?

I play on using my computer to (upload) HD broadcast through a webcam (Logitech C920). I'll be using an Ethernet connection with 50mbps download, 10mbps max speeds. I haven't built or ordered any components yet, budget is around $750. I am looking to get the highest quality video possible from the webcam, I have been using it on a laptop with slower (internet) speeds, and lower resolution on the webcam, (a6-5310 processor on laptop) I notice high cpu usage (of course). The website recommends an i3 or better processor for broadcasters. Also, I will be using a 50+" tv for a main display, and I am not sure if it would be a requirement to get a video card (to take the display requirements off of the cpu) or if the cpu will be able to handle the two things I am asking it to do with ease? Will not be used for gaming^^^

What I am thinking so far.
i5-6500
cheap h110 mobo
16gb ram 2x8 ddr4
video card or no?
while not a real concern I would like to keep heat/power low?
should I get a smaller ssd or larger hdd?
quality psu recommendations?

lots to this question, but mostly interested in the question will the i5-6500 be enough to broadcast hd stream from a webcam and display on a 50"+ tv?

If your broadcasting software does support offloading to dedicated hardware, CPU load would barely be a question (consult your broadcasting software developers site/forums for this, Quick Sync is the term for Intel HD Graphics hardware decoding).

The integrated video on the i3 6100 and i5 6500 is the same Intel HD 530 with exactly the same clock speed and it does support hardware encode/decode FullHD of h264 (aka AVC - Advanced Video Coding) i.e. the most common high definition video codec as well as the h265 (aka HEVC - High Efficiency Video Coding) that was developed to maximize bandwidth/quality efficiency for online streaming (support for h265 in streaming is still very limited, probably due to lack of compatibility with older...

If it doesn't, then the need for an i5 is warranted. On the videophile corner of the internet, there are people arguing about software (and therefore CPU demanding) based en/decoding produce better video quality compare to hardware based, but to the average folks, they'd be hard pressed to tell the difference.

Without a dedicated graphic card, an i3 6100 system would only consume ~100W under load; an i5 would need a bit more.
So a Seasonic S12II 350W would be sufficient for your need.

An SSD should lower power consumption so assuming you aren't looking to save/preserve your HD broadcast, an SSD could be the better choice.
