Sticking to its veteran product lineup strategy, Nvidia released its GeForce GTX 1660 mid-entry-level version of its current Turing-generation graphics cards to fill the $200-$220 price band currently occupied by its GTX 1060. That gives it two graphics cards with the Turing architecture in the $200-$300 range after Februrary's launch.
While there are rumors of a GTX 1650/1650 Ti, which would be the true entry-level cards for populating budget gaming systems currently using the GTX 1050/1050 Ti, there's been no official word. No rumbles about a 1670 as yet.
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.
