What games are you expecting to play and on what settings? On that website you linked 700 dollars will get you and AMD X4 840 cpu not really that great for modern games and a gtx 950 which is the weakest of nvidia 900 series, paired with literally one of the cheapest amd motherboards out there and a terrible power supply. That might be okay for say a 500 dollar build but not 700 thats ridiculous in my opinion. If it were me I would just get a ps4 and save 350 dollars the gaming experience will likely be similar anyway. Or maybe look at used systems.
