Both 1660-model cards are targeted at delivering decent 1080p gaming performance. As Tom's Hardware's test results show, it pushes some more games over the 60fps line where the 1060 it replaces fell short -- it looks like the gap is wider for DirectX12 than DirectX 11 -- but if you're going to want to step up to 1440p in the near future, it probably won't serve you very well and the Ti version would be a better option.
