Wow, consider me impressed. Not only does the TwinView work with my Linux box, but OpenGL also renders on both monitors. I tested this with OpenGL screensavers like Atlantis and GLPlanet. Thanks nVidia, this is a great product. I will certainly be boasting to my buddies at work! I just wanted a dual head card that worked well under linux. Heck, I got a card with awesome OpenGL performance as part of the deal. This rocks!
