$1000 gaming PC 2015 (including os)

Solution
The i5 4690 is a terrible value. The Xeon adds hyperthreading for just a little more. It's a great cpu. If you don't want the Xeon, get the i5 4590.

The Corsair CX psu is also not very good.

Swapped the 4690 for a Xeon 3.4Ghz quad core w/ hyperthreading, nearly the same price. Went with a more reliable and reputable power supply. For the price you were paying from Amazon you can even afford to go for a little higher efficiency or perhaps a modular power supply.
