It's an excellent gaming build.
Here's a couple suggestions that you may feel free to ignore:
-Get the lower wattage variant,
---Saves you some monies.
-Get a high-end air cooler such as the NH-D14, Dark Rock Pro 2, PH-TC14PE etc.
---Saves you some monies, high-end air coolers tend to be superior to 120mm AiOs in almost every aspect (acoustics, performance etc.)
-Get a 1440p monitor such as the U2713HM or cheap Korean monitors such as the Yamakazi Catleap.
And one last thing, 8 RAM sticks on a Maximus VI Gene... Interesting...
