First Build - Sub $1000 machine

Hello,

I am seeking the community's take on my first build, a machine I will use for photo editing, some gaming (Civ V, and the like), and music storage and playback.

Any thoughts, suggestions and comments are welcome. Any glaring compatibility problems would be appreciated!

Here's the build:

Cooler Master Storm Scout SGC-2000-KKN1-GP; ATX Mid Tower Case

Antec High Current Gamer Series HCG-750 750W ATX12V v.2.3 SLI/Crossfire Certified, 80 Plus Bronze

Gigabyte GA-990XA-UD3 AM3+ AMD 990X SATA 6B/s USB 3.0 ATX AMD

AMD Phenom II X6 1100 T Black Edition Thuban 3.3GHz, 3.7GHz Turbo Socket AM3 125 W Six-Core Desktop Processor

G.Skill Ripjaws Series 16GB (4 X 4GB) 240-Pin DDR3 SDRAM DDR3 1600

EVGA SuperClocked 01g-P3-1367-TR GeForce GTX 460 SE (Fermi) 1GB 256-bit GDDR5 PCI Express 2.0 X16 HDCP Ready

LITE-ON 24X DVD Writer Black SATA Model iHAS424-98 Lightscribe Support

I have an existing, identical WD HDD which I will be using as a backup in my new machine.

Thanks.
