Nvidia initially may have been a bit disillusioned at what kind of premium gamers would be willing to pay for features that are not yet widely adopted, hence why sales of its GeForce RTX 2080 Ti, 2080, and 2070 graphics cards have not met the company's expectations, as it candidly admitted recently. But then came along the GeForce RTX 2060, a more affordable entry into the world of real-time ray tracing and Deep Learning Super Sampling (DLSS). For gamers in need of an upgrade, the GeForce RTX 2060 is one of the best graphics cards to consider, and is a clear winner over the similarly priced GeForce GTX 1070.

Now comes along the GeForce GTX 1660 Ti, however, and suddenly the choice is a bit murkier for anyone with a few hundred bucks to spend on a graphics card. It doesn't boast the same bells and whistles as Nvidia's RTX cards, but it does trounce the previous generation GeForce GTX 1060, and does so at a palatable price.
