You are a gamer as well as streamer so i will definitely want you to have a 6 core cpu (you can go with ryzen 5 2600 or ryzen 5 3500) In this price segment, the best gpu i would like to suggest you is gtx 1650 super (including cpu and gpu the 350 dollar will complete. Should fo with ryzen 5 1600 if with ryzen 5 3500 it's getting costlier than 350$ (suggestion - you can also go with gpu rx - 570 or gtx 1650 which feels you comes in price range as i don't know what price is going on in your country if it's fine with 1650 super then take it without any doubt) Go with 8 gb ram (corsair) You can upgrade it in future with another 8 gb ram stick (16 gb ram in future) Motherboard - msi vdh pro max In this check that if it supports ryzen 1st, 2nd , 3rd gen processers, if not then don't go with ryzen 5 1600 as it's first gen but if you are feeling costly then check a motherboard that supports 1st gen ryzen Psu- 450w (more than enough) If you are not going to download many games with big size then go with ssd 240 gb but if you are gonna download them (games like gta v watch dogs pubg wither 3 morder cod games......) then go with 1 tb hdd Take a cabinet of 40$ or less They are the priamary components you will get under 600$ mouse keyboard monitor are secondary if you are gonna buy secondary as well in 600$ then you can compromise with gpu, cpu and motherboard
