I just wanted to say thank you for your guide. This was the first time I tried to build such a machine and once you understand the whole system it is really easy to get a successful install thanks to your guide : )
The only thing that was a little difficult for me was the video, I think I will try your updated guide with the RC3 Nvidia auto detect (I have a 9600GT).

(Right now I have just added the efi string in the boot plist because I did not understand what kext and so I need. Resolution and average use seem to work fine but cpu load on 720p video for example is very high (50-100%))

So my actual question would just be if I did understand it right that with the RC3 Nvidia auto detect you dont have to do anything more or do I still have to do all that kext and efi string stuff?
Thanks a lot
greetings from germany : )
