My MACPRO was a build to order, and the original 2008 had 2 core processors. My model only has one. From the literature I've found on the net, everything is the same (motherboard, , etc..its just missing a processor thats all.) So im assuming its really just a matter of dropping in the new processor, thermal grease, and a heat-sink does anyone know any more information on how to do this? I've found the processor online, but I don't know if its the "correct" one? I'm having trouble finding any more information on this actually. Please help!
