i5 6500( or 6600k, or i7 6700k budget allowing) with H170 or Z170 motherboard + 16gb DDR4 ram
High quality 500w-650w (depending on the choice of components) PSU (EVGA/Seasonic/Superflower/XFX etc)
GTX 1060 6gb or RX 480 8GB (again could go to a 1070 or 1080)

Is the SSD and new motherboard necessary ?
