Not sure if this is the right place, but here goes: Why don't computers have more than 2 processors? Instead of 2 quad core processors, why not 8 1 core? I know that would be expensive. The Power Mac G4 had dual single core, so why aren't there quad or more single core processors? If any computers have ever had more than 2 processors, let me know about them, please. Any insight is appreciated!
