    Does a mac pro have two power ports? I know I need an adaptor cable, but can I use two? Is there two ports on the logic board?

    6970 is a handful, in most OSX versions it needs a hack to work

    There is an EFI64 rom for it so it is possible to get boot screens on DVI port in a 3,1 or later, but the hack is more trouble than it's worth.
