Need advice/suggestions/opinions on my PC build

[Sondag79]

HELP MEHhh please!! I'm a very amateur PC builder. I'm currently upgrading a PC and need any feedback/suggestions I can get. (I'm open to any and all suggestions) I don't upgrade my PC very often so I want this to last me for a very long time. I need to buy 4 things. Those being a motherboard, processor, RAM, and graphics card. This PC is strictly for gaming (BF4, Dayz) and have a budget of $800. I have put together the following but I would greatly appreciate any feedback/suggestions regarding these choices:
http://pcpartpicker.com/p/zdt9wP

Motherboard: $95 ASRock Z97 Fatal1ty Killer ATX
Processor: $200 i5-4690k 3.5GHz.
RAM: $150 Crucial Ballistix Sport XT 16GB (2x8GB) 1600 CL9 9-9-9-24
Graphics Card: $270 MSI Radeon R9 280x 3GB
I've went in store and had a price quote for these 4 things for $780 w/tax

Would it be better to get 8GB (2x4GB) RAM with a higher speed 1866-or higher 2400? Or am I better off going with 16GB? Keeping in mind that I'm trying to keep this build as much future-proofed as I can so it will last me for several, several years to come.
I'm open to any feedback and/or suggestions so please, please please fire away and lay it on me!
Thank you in advance for the help. 😛

8 GB of ram is more than enough right now, and speeds higher than 1886 dont give much of a performance boost, also post the psu, thats a very important component that most people ignore, getting a low quality psu in a build can doom other parts.

Take a look at this:
