i would revise that build and you are missing an professional audio interface as well.
here's some opinion from my POV with a $1000 budget, assuming tax/shipping not included.
-CPU i5/i7 ivy bridge
-Motherboard Sub $150 Z77/Z75
-GPU HD 7870+ or HD7950 or HD7970 or GTX660ti or GTX670
-RAM Dual channel 1600mhz
-Cooler: Closed Loop liquid or some better Cooler of $50+
and everything else looks good.
