$1250 Gaming PC

Solution
You are in good shape. My thoughts are below.

CPU Cooler - Added water cooling
MEM - ...not included in your build. The modules below are low latency DDR3-1600 CL8

GPU - The MSI is clocked higher and is a bit more quiet.
PSU - The 550w Gold is great, but not exactly needed. The 650w below gives you a bit more headroom to grow and still an excellent unit.
