Hello, I am building a gaming PC and I was wondering if there was any place where I could improve on the parts. Also, if you think there is a spot where there is a cheaper part that gives that same performance, thats great! The PSU is 750W because in the future I will get another 970, thanks! http://pcpartpicker.com/p/KYPP99 ( also have Windows 8.1 and a 1TB HDD)
