PC Build Help Needed!

I really like these build plans, but before I invest money into it I would like to know if there is any way the price can brought down while maintaining the same performance.  Any and all input is greatly appreciated.  This pc will be used mostly for gaming.  My max budget is $1500 but I would like to save all I can.

My build: http://pcpartpicker.com/p/INpg

Thanks ahead of time.

16gb of RAM is useless for gaming. you would not see any performance decreases with 8gb
