Advice on Bolt 3 Build

Budget:
2000-2700

Expectations:
1080p Max settings for gaming

Usage:
Highest usage will be for gaming, but will be for general usage as well. Fallout, Skyrim, etc.

I have the specs down below, but there are some changes I would like to make and your opinions on those changes.

RAM: G.Skill Ripjaws X Series 16GB (2 x 8GB) DDR3-1600 Memory
Second HDD: Western Digital Caviar Blue 1TB 3.5" 7200RPM Internal Hard Drive
GPU: Asus GeForce GTX 980 Ti 6GB STRIX Video Card
PSU: Corsair RM 650W 80+ Gold Certified Fully-Modular ATX Power Supply

I'm pretty sure the RAM will be the only thing that needs to be special ordered. I don't want the Corsair Dominator, and the only other option is the DS RAM. Is their RAM just fine? This is my first gaming desktop (i've had several laptops). Am I going overboard a little with some of the options, probably, but for first time desktop I want to get something really nice. Let me know what you guys think about the build and my changes.

Thank you

Thanks for letting me know! I'll search around for some if not, I'll stick with the 8GB DS RAM. And the GPU, yea I know lol. First build so I'm going big on the gpu. And a little future proof too. I might upgrade monitor as well so would be nice to be ready for that.

Thank you!
