Any suggestions on improving my pending build

[straifer125]

I am currently looking to build a new gaming pc with a budget of $2000-$2500. I am unsure if the build that I am getting will be the best bang for my buck or if I am over/under shooting what I need for my build. Here are my current specs. im going with:
Total: $1984.74
CPU Intel Core i7-4770 3.4GHz Quad-Core $289.99
CPU Cooler Cooler Master V6 GT 93.7 CFM $49.99
Motherboard MSI Z87-GD65 Gaming ATX LGA1150 $154.99
Memory Crucial Ballistix Sport 16GB (2 x 8GB) DDR3-1600 $133.60
Storage Corsair Neutron Series GTX 120GB 2.5" SSD $120.98
Seagate Barracuda 1TB 3.5" 7200RPM $59.98
Video Card EVGA GeForce GTX 780 3GB $509.99
Sound Card Asus Xonar DSX $49.49
Wireless Network Adapter TP-Link TL-WDN3200 802.11a/b/g/n USB 2.0 $23.79
Case Corsair 400R ATX Mid Tower $69.99
Power Supply XFX 850W ATX12V / EPS12V $114.99
Optical Drive Asus BC-12B1ST/BLK/B/AS Blu-Ray Reader, DVD/CD Writer $56.99
Operating System Microsoft Windows 7 Home Premium Full (32/64-bit) $199.99
Monitor Asus VE228H 21.5" $129.99
Keyboard Gigabyte Force K3 $19.99

I am all for adding better parts or changing parts for a better system, keep the <$2500 in mind.
I will be playing BF4 and other shooters on my new build along with some RTS games. So, if you guys have any suggestions let me hear them.

Thank you

very good build
it is a revision of your build, with better price/performance parts selection
i7 isnt the best band for the buck. gaming only need i5
