I was looking to make a pc build around 500$~ I took the idea from https://pcpartpicker.com/guide/cJWG3C/entry-level-amd-gaming-build, but I already had some parts which include (SSD, HDD, 8GB Ram 2666, and a ryzen 3 1200) I was wondering if it would be best to upgrade to a ryzen 5 2600, or if I should look to swap something else out. For graphics, I am able to get a GTX 1070 for 215$ so that to take that into account I would have somewhere around the 300$~ budget left for a case, PSU, mobo. Also forgot to mention, but the pc would be used for light gaming nothing heavy, (Overwatch, League of legends, Destiny 2), video streaming, and basic web browsing.
