$699 USD is a lot to spend on a graphics card, but damn she is a beauty. Last month NVIDIA launched the GeForce GTX 1080 as the current top-end Pascal card and looked great under Windows while now finally having my hands on the card the past few days I've been putting it through its paces under Ubuntu Linux with the major open APIs of OpenGL, OpenCL, Vulkan, and VDPAU. Not only is the raw performance of the GeForce GTX 1080 on Linux fantastic, but the performance-per-Watt improvements made my jaw drop more than a few times. Here are my initial Linux results of the Gigabyte GeForce GTX 1080 Founder's Edition.
