okay, i'm preparing my movie collection for the apple tv 3 that i'm going to buy. I'm using subler and handbrake to encode movies to mkv. A typical avi (1-2 gb) takes me around 25 minutes to encode with my alu macbook 2.0 core 2 duo, 4gb ram. How fast will an i7 do this? Can someone time this for me? Will an i7 do this in like 5 minutes? Or 1 minute? Main question, how much really faster is a mac mini i7 than my macbook 2.0 in real life situations like encoding movies ... Edit: not to forget to mention this, what about fan noise? Right now my macbook is going insane with the fans while encoding an avi file ... Thanks!
