What are you using this rig for? If you are just gaming on a single monitor, everything is overkill. For a single monitor, you will not benefit from anything more than a GTX 770. I recommend the i5-4670k, CM Hyper 212 EVO CPU cooler, and an EVGA GTX 770 w/ACX cooler for gaming and overclocking. If you are video editing on a single monitor, replace the previous list with an i7-4770k. If you already have and/or bought the GTX 780Ti, then pair it up with the i5 for gaming, i7-4770k for gaming/light-medium video editing, and i7-4930k only for dedicated video editing and/or gaming at 4k resolutions on multiple monitors. I will also recommend selling the 780Ti and getting money back if you are only using between 1-3 monitors.
