Greetings all, I'm in the process of upgrading my 3,1 machine, and as it so happens I've got an extra heatsink laying around that will fit. I want to buy a matched pair of quad core Xeons to convert my formerly quad core 3,1 machine into an 8-core. I would prefer to buy CPUs that would be correctly recognized by Mac OS X, and now show "unknown processor". Is there a list I can find of CPU IDs that can aid me in shopping? Perhaps inside some kext? Help is appreciated, thanks.
