I have a Gigabyte Z97X-UD5H with 16 GB ram with an i5-4670. I use it to livestream to YouTube and I have noticed that the CPU load is about 50% plus or minus. Will upgrading the CPU help or will I notice any difference? I am looking at an i7-4790. BTW, both the i5 and i7 are quad core and I am using an nvidia GTX 1060 video card.
