If I buy i5 4670k and nvidia GTX 770 2gb then what cabinet, PSU, cooler and motherboard would be best for me to assemble? My 'cabinet+cooler+PSU' budget = 10000 to 15000 INR, motherboard budget=8000 to 12000 INR. Also, Is RAM 16 GB necessary for high end gaming computer? or 8gb is sufficient for games? Plz help me guys.
