Thoughts on this hypothetical PC build?

I'm hoping to make this in the near future, and I'm just trying to make sure that I'm getting the absolute best quality/value ratio.

This setup would be hooked into my living room 1080p system, so ideally it would play games like these in 1080p with the highest settings:

TES V: Skyrim w/ mods

Fallout 4 (Someday!!!)

Star Citizen (or other games using CryEngine 3)

Unity 4 engine games (specifically thinking of Starry Expanse, whenever that's ready)

The thought is that this setup would be almost top-notch for the next 2-3 years, at which point I'd throw in a second 7970 GHz Edition to give it a substantial boost. I'm not afraid to dabble in some overclocking either, hence the more robust liquid CPU cooler.

Thoughts? Any suggestions on how to eek out more performance for a small price?
