Best answer: The choice between an NVIDIA GTX 1060 and GTX 1070 GPU depends on your display. If you’re rocking a 1080p monitor, you can get away with the GTX 1060, but 1440p and above requires more performance. The safe bet is to go for a GTX 1070 if you can afford it.
A match made in heaven
The GTX 1060 range of GPUs are great affordable cards for those on tighter budgets, but the cards are also matched perfectly with 1080p resolution displays. Gaming at Full HD isn’t too demanding on the system as a whole and you could get away with a less capable card (and therefore save money in the process).
However, should you have a Ryzen 5 2600 CPU installed, the GTX 1070 can really shine bright, especially when hooked up to a 1440p display with a refresh rate above 60Hz. The CPU is capable of handling most demanding titles and should be good for many years to come, which is exactly the kind of partner the GTX 1070 GPU requires.
