"Is $5000 powercord really necessary?" Of course not, unless you really enjoy being someone's fool. If it were the case that dedicated lines cost this much (instead of 1/10th, as they do) I would be willing to say yes. The difference in this respect is indeed dramatic. But power cords - no way.
Interconnects and speaker cables, that is a different story. These have made a big difference for me. But there is no exact relationship price and quality of match in a given system. It is still easy to be a fool unless you know your own mind and trust your own ears. And personally, I would never spend anything close to $5k on a single cable or wire.
