Well got my Turbo.264 in today. Did a speed test vs my Mac Pro. Mac Pro specs Quad 2.66ghz Xeons, 5gb ram, 500gb 7200rpm HD Mac Mini 1.66ghz core duo, 2gb ram, 100gb 7200rpm HD - Mac Pro Video sample pulled from 500gb 7200rpm HD internal. - Mac Mini Video sample pulled from 250gb 7200rpm HD firewire external. - Video sample. 1hr and 1min. - Compressing to ipod default 640x480 H.264 TIMES - Mac Pro 1:07:37 - Turbo 1:20:17 So not as fast as a Mac Pro but not bad. Despite what people say, the Turbo does use 60% of your cpu while in use. That is for both cores. Fans spin to 3840rpm in the mini. So basically not a great option if you have a mac pro but not bad.
