NVIDIA's GeForce GTX 1070 is nearly twice as fast as GTX 970, easily beats the $1000 Titan X, and GTX 970 SLI, at only $379/$449. It is built on the same platform as the GeForce 1080, using the same GPU and cooler, just GDDR5 memory instead of GDDR5X. As expected, power efficiency is amazing, and overclocking works well, too.
