Question: is gtx 1660 better than 1080?
Answer: NVIDIA's 16-series GPUs were made to be the perfect 1080p gaming solution at a reasonable price point, but I'd venture to say that the 1660 is good for light gaming at 1440p. Basically the 1080 is much better. RTX 2070 can outperform the old GTX 1080 but even RTX 2060 comes close to it.
