Where graphics card? If it doesn't have one, there's your easy upgrade. However be aware that prebuilts have terrible PSUs so you'll likely have to replace it.

It's in the cpu, the G series of ryzen chips have a igpu, the 5600g is about equal to a gt 1030 if I remember right, maybe a 1050 I don't exactly remember but right around here

OP has a 5700g, so it can run 720p 30fps in most games
