Soppie, I have the exact same system and the move to 1050 is noticeable. I then upgraded to 1060 with yet more noticeable difference. If you decide on 1060, go for the 6GB version, it is a little more expensive but makes big difference for the more recent games especially for the high-res textures. And I also hear it is slightly faster than the 3GB version. I didn’t have to upgrade the power supply when I went with the 1050. By the time I switched to 1060 I had a different power supply, so can’t speak to that. As I remember, the original PS was rather weak to begin with.
