Gaming/General Use Build <700$ [UPDATE]

My current desktops very dated and I was considering building my own just for the fun of it and to save a bit of money while still building a powerful system. This is my first build, but I have confidence that I can build it without too much trouble. I have a strict budget of 700$ not counting the OS, keyboard/mouse or monitor. Any tips/suggestions regarding the parts? Anything I missed?

Intel i5 3450 195$

PNY Optima 8GB (2x4GB) 240 pin DDR3 1333 35$

ASRock z75 Pro3 85$

Corsair Builder Series CX430 45$

PNY GTX 560 Ti 1GB 160$

Western Digital WD Black 500GB 7200RPM 90$

Corsair Carbide Series 300R Black ATX Mid Tower 65$


[UPDATE]



Decided I would spend a bit more after going back and forth a bit on the GPU and CPU. This is the build I was considering. Any suggestions?
