For 1080p videos, i7 will have more advantage. The more resolution, the more processing power needed on each render.
It also depends on the codec. Uncompressed RGB is really slow, while UT 420 is really fast.
You can consider the FX 8350 too. It behaves like a 3770k in video rendering for half the price.
The time it takes for final rendering is not an issue. I am most concerned with how smooth video building is going to be (organizing, trimming and viewing clips in the timeline)? And I want a processor that fits into 1150 socket motherboard that I have already.
