I need the expertise of the my gaming community to help me build my first gaming pc. I don't want to spend more than R9000 excluding a monitor, keyboard and mouse. I want the pc to be superior/on par with the ps4. I've always been a console gamer and i sold my xbox when the ps4 was announced but i was later put off by its media capabilities or should i say incapabilities(i was really disappointed cause i really wanted a ps4) . From my research on pc gaming components I've come with a budget for very good gaming pc.

Gpu: R4000
cpu: R1500
ram: R1000
mb: R1000
hdd: R1000
chasis+psu: R1000

I want it to be able to play most games on ultra at 1080p and room to upgrade in the future. This will be my first rig so i really would appreciate all the help i can get.
