why not just spend on extreme i7? obs, relive, shadowplay arent really taxing at all, its just configuration
You're always going to be just fine with a regular i7, but it's only 'just fine'. Having a Youtube tab open, a few background processes and so on, there will be fluctuations. If you're playing an extremely heavy game like BF1, you're going to momentally hit the cap of available processing power eventually when OBS happens to hog more juice at the same time.
Having an old i5 computer do you the job (or a retired server setup) will remove those lagspikes caused by CPU encoding, and does it well.
I have a few active streamers in my friends and most of them use a i5/i7 and do just fine and dandy. I have spent considerable time in order to help one of them enhance their stream quality and have often come to a performance wall with the i7. That encouraged me to try to push the limits of the i7 6700K as well - only to come to the conclusion that the setup is good, but has it's limits.
And meanwhile one of my mates just walks to a house-LAN with a spare laptop and uses it for encoding, resulting in a hitch-free better-looking stream and never has hickups or frame drops in-game. And that's a mobile i7, 2000 series.
Go figure.
