So Nvidia just announced their new line of GPUs, and they look pretty amazing.
The GTX 1080 is supposedly faster than 2 GTX 980s, making it much better than the Titan X, and will be US$599 on launch.
The GTX 1070 is supposedly equal in speed and power to the Titan X, but for 1/3 the price, US$379.
More details here.
I’m now in half a mind to sell my 970 and buy a 1070, as the price difference is pretty slim for much better performance.
