I have a Base 2.3 Mini with 2GB Ram, and this thing Encodes 8 movies in the time my 2009 C2D 2.0 GH with 4GB ram encodes 4, I did not realize how fast the new i5 CPU's work. I just wish there was a way to remove Lion and put SL on there with no issues and no hacking, if Apple allowed this it would be cool, not really liking Lion much.
