First of all, I'd get an MSI Twin Frozr 7950 if you can - much better quality than Sapphire, and is a true 2-slot card, where the Sapphire Vapor X is slightly too large for CF.
Secondly, that PSU is much too large. Unless you plan on adding two more 7950s, you don't need more than a 550W PSU, like a Seasonic G 550. If you want room for a second 7950, I'd get a nice 650W, like a Lepa G650 Mas. For a single 7950, even with both CPU and GPU overcockd, you don't need that much power.
For the love of Jeebus, don't get 2GB sticks of RAM. At the very least, get 4GB sticks. You don't want to limit yourself in the future - with 2GB sticks, the most RAM you could ever get is 16GB, despite your board being able to handle 64GB. However, the Trident X series of RAM is still fantastic - I'd keep it, just get an 8GB kit or 16GB with 4GB or 8GB sticks.
The Corsair H100i is really overpriced - switch it out for a high-end air cooler for equivalent or even better performance, but for less money. My go-to cooler is the Phanteks PH-TC14PE, which is what I have in my personal rig. 4.8gHz, 1.43V on my 3770k, maxed at 73 C under IntelBurnTest, small FFT. Great cooler, great looks, and color options.
The Corsair 200R is a really low-end case. By switching the things around I mentioned earlier, you should have enough room in your budget to grab a nicer case, such as a Fractal Design Define R4 or Arc Midi R2. Both will complement your high-end rig well.
Other than that, I feel obligated to recommend the AMD 8350 and a Gigabyte UD5 990FX instead of the UP4 X79 and 3820 if you don't plan on getting more graphics cards.
