Asalaam walikum. It seems you have insufficient knowledge regarding computer hardware in general. I suggest you get some knowledge before jumping into gaming zone business. Just a food for thought. Anyways best of luck.
Ma Sha Allah. Congratulations, hope it serves you well enough. Why 970s you could have gone with 2X 8gb 290X for true 4k experience for less money. Anyways, enjoy gaming.
I recommend you to get Headphones, Superlux 668b Semi open headphone. Of if you wanna get speaker anyways better get logictech z906 or probably some Creative Gigaworks series.
Asalaam walikum.
-Get an i5 2400(used) for 11-12k or i5 4590 (new)
-Get any B75 mobo for i5 2400 or h97 for i5 4590
-Get AMD Non reference r9 290 in warranty (new/used) or import Nvidia gtx 970 (asus/msi/gigabyte g1) for $320+ excluding shipping charges
-Get kingston value ram DDR3 8gb 1600mhz...
Asalaam walikum!
Kane get 970 but first get atleast 2nd Gen i5 else your cpu will bottleneck, psu is fine thou. Jetfire get Transcend 256gb @ 14.5k from Galaxy
