How can i make my build cheaper without taking away performance?

[ImWithBae]

Here is my soon to be first ever gaming pc: http://pcpartpicker.com/p/D2Lt23

I am looking for a way to bring it down in price without taking away any performance. I alreeady asked on the forums on pcpartpicker and got literally no response. Hoping i have better luck here. If there is any way to also match the color scheme of the case that would be nice.

You could lower your price by getting a lower power PSU- you really only need 500-600w for the components you list. You could also save by buying a used GPU. You can get a 290 for around $200 on ebay.

Could drop back to Windows 7.

Then upgrade to Windows 10

knocked about $100 off the price by getting a cheaper mobo/ ram and case. won't see a performance hit at all. psu is more power than needed but after rebate for the price there is nothing better.
