With the new "Release 80" driver, NVIDIA takes SLI to an entirely new level. First of all, gamers can use graphics cards in SLI mode with different clock speeds, different BIOS settings, different input/output configurations, different memory sizes and from different manufacturers. That means that our friends Nick and Jeff can buy any graphics card they want, as long as it's the same model as their current graphics card (GeForce 7800 GTX for Nick, and GeForce 6800 GT for Jeff). How's THAT for flexibility?
