I want to upgrade but i want to keep my asus strix gtx 960 video card 2gb, ocz 700 watts power supply, and my benq monitor 240hz. i want to play my pubg with no graphic degrade and any game i can enjoy, with my current set up its not great. its my first build and dont know whats good back then. maybe i could spend about 600 to 700 us dollar, mainly for mother board, memory, storage etc to complete it.
