Transitioning from 4930k to 8700k
How was this diagnosed? If you purchase it at the current market rate now but plan to use it only in four years, then yes—it's a waste of money. In four years, you might find a better option available at a lower price considering market trends. You're free to choose what you want, just keep in mind we don't advise this—after all, that’s what you were looking for when you asked.
You're considering upgrading from your current setup. The I7-4930K works well on your ASUS P9X79, but switching to the I7-5960X on your MSI X99S Gaming 7 could offer better performance for your needs. Since you mainly use it for 3D rendering in VRAY and gaming occasionally, a mid-range processor should provide a good balance between speed and power efficiency.
