Should I upgrade my CPU or GPU

[Flameidge]

Hello everyone. I want to upgrade my PC but I don't know what to upgrade first, my CPU or GPU. My CPU is an AMD A6-6400K. And my GPU is an AMD Sapphire 240 4gb. What do you guys think? Any answer is appreciated

I would do the GPU first, I think the cpu will be fine. Most games require a demanding GPU.
