You should absolutely upgrade. Maybe the whole thing. If your budget is lets say the cost of a RX 5700 XT which is 450~ you can easily upgrade it for some good performance. You have a case and PSU so Ryzen 1600 AF, some B450 mobo, 16GB of RAM, and a RX 5500 XT and your hovering around 425-450 territory my friend. It'll perform so much better and you can even stream because 6 core.
