I'll tell you this much. Probably too long for you to be bothered to do so.
Rendering with my I5-4590 took around 1 Hour, for a 5 minute video. Explains a lot aye.
If you want to render videos quickly and successfully, go with an i7, the Hyperthreading will allow you to render a video at the rate of around 2 Minutes for 1 Minute of footage (At the beginning) and it may slow down after a while depending on your cooling.
