I have a few suggestions, if I may. I have custom built several gaming PC's, and have a bit of experience .
I would recommend a much different GPU...while that one is a powerful card, it actually doesn't exist. It was a trial card made to demonstrate nextgen graphics computing.
In my experience, XFX is the most powerful and dependable GPU manufacturer, and this card will wow you. It runs at 1.0 Ghz, and can overclock to 1.2 or more, making it the fastest GPU on the market. It is the XFX Double D Radeon HD 7870 card. It has 2gb of GDDR5 memory, and can run any game on the market at max FPS at well over 1920x1080. It uses a PCI 3.0 interface, and has two built in fans, so the hybrid LCS cooler will not be necessary It is available on Newegg for $250.

I also recommend a different case. The one I suggest is one that I use for my PC. It is unique because it has a bottom mounted PSU. It boasts several massive fans, and many ports in the front and back for almost any mobo and can hold quite a few DVD players or anything else you want to install. Also, it looks badass with the blue LED's. It is a true beast of a case, and the price reflects it. $219.

While the G.Skill Ripjaw memory is superb, it has a maximum clock speed of 1600 mhz. This would interfere with and even slow down your i7 and GPU's extremely fast clock speeds. I would recommend the faster G.Skill memory, such as the G.Skill Trident. They have a 2400 mhz clock, which is significantly faster . It is priced at $139.
