Again , read the wiki and search the forums of insanelymac. JUST USE THE SEARCH Function , its all there . Like I said , you need to have some 1337 knowledge on how to install kexts and stuff like that.
Again OSX has drivers for NVidia cards , all you need is EFI Emulation for it. Thank god , Jas' DVD And Tubgirl comes with them. So you just tick them and it will be installed for you
If you're looking for custom drivers made by a friend of mine ,DiaboliK . He has made it soo easy , then check out his site

Again , you need to check what is causing waiting for root device...If you're installing on a 965P mobo , it will not work
I say if you're not up for this challenge , go ahead and get a mac. It saves you all the time and hassle !
