My rig : i5 4560 3.1 ghz 4 gb ram nvidia gt 610 2gb I am thinking to buy a new graphics card. But I am confused which one to buy from amd and nvidia . My budget is rupees 15000 . I thought I would buy evga gtx 760 2gb but can it play games such as watch dogs , assasins creed , gta 5 at ultra settings ? IF necessary i will increase the ram to 8 gb. Please reply ASAP! THANKS!
