Help to find out motherboard GPU OR Video card

Hi Guys,

I am Planning to build a new Machine. I have decided to go for Intel Core i5-2500K CPU(price 85 Rial=$218) and corsair (2x4)8GB ram (price 28 Rial=$72). But not sure which motherboard GPU OR Video card to buy? How to set up my system?

so that i can watch Blu-ray 3D movies in the most cinematic style possible.

and playing game. like NFS, MOTOGP, FORMULA 1 CALL OF DUTY. ETC

Thanks in Advance!!
