Recently, I was thinking about upgrading my gpu, but I'm a little unsure what model makes sense. My system is quite old, but I am also (modt of the times) not a lot of an ultra graphics gamer.

My system:

CPU: Ryzen 5 3600 Mainboard: MSI B450 mortar max Gpu: gtx 1070 Case: Fractal design define mini c Power: Be quiet! Pure power 500W Atx

Actually, I want to switch to linux in the future, so I tend more to the AMD direction.

I have a budget of around 400. But I was also looking for something that isn't too hard on the power bill...

I don't need the newest stuff so does instance a rx 6700 make sense or would you say just changing the gpu isn't enough?
