Questions:
Anything I need to switch to make it cheaper but still have the same performance?
Will everything fit?
Do I need to change my PSU?
Thanks in Advance

I picked a little cheaper 970 and one that matches your case colors. Changed the PSU for better quality. Other than that, great build!

Everything should fit. I would recommend a GTX 970 MSI Gaming. Your PSU should be fine, even though I prefer Evga or Seasonic PSU's. http://pcpartpicker.com/p/H4kYvK
