So I'm looking to upgrade both my cpu and gpu. I want to purchase a GTX 770 for sure. So my main question is should I save money and buy a 3770k or buy a 4770k along with a new motherborad. My current mother is compatible with the 3770k. But I don't know if I should spend the extra money and upgrade my motherboard along with the cpu, it doesn't matter which cpu I get I will be overclocking it. Also I use the PC for live streaming games and video editing.
