Can my current PC specs handle gaming+streaming?

I'm planning to build a new streaming/gaming computer. I'm not confident thatmine will be able to handle it.

I currently have:

• AMD Ryzen 5 2600 3.40 ghz
  
• 32 GB DDR4 RAM 2666mhz
  
• Radeon RX480 Graphics card 8GB DDR5
  
• SSD drives
  

What do you think? Can it handle gaming+streaming?
Or should I upgrade something?

I will just stream a lightweight game: Ragnarok

Let me know your thoughts!
