I'm running an SLI set up on my GTS 250's. I'm using the 191.07 drivers and my screen is flickering like crazy. Just sitting in my desktop it'll drop the image for a second and then come back. It was 10x worse with the newest drivers so I rolled back to these drivers (which worked, but then I reinstalled win7 for my new HDDs). Could my HDMI cable be going bad possibly, or is this something else do you think? W/E the problem is I've got a v1.4 hdmi cable on the way and if that doesn't fix it I'm selling these and buying either a radeon 5850 or 5870.
