New leaks reveal that Nvidia's GTX 1180 will support higher refresh rates through one VR-friendly connection, making it possible to render 4K@120 Hz content for each eye, and this would also apply to the TV-sized G-Sync 4K monitors. Price-wise, the GTX 1180 will not match the original launch MSRP of the GTX 1080, as there will be two versions and the most affordable one is supposed to cost US$999.
