You know what I find? People that complain about drivers in general don't even own the product they're talking about. I have both ATI (6970's) and GTX 580's and have not had a single driver issue with either card, with the 6970s that I had since release in Dec 2010. Whats more, AMD is actually *more* timely in general with having updated dual/triple GPU profiles for their cards. I'm guessing you heard from a friend of a friend of a friend that posted about it on the internet? Rage fiasco? Whatever, bethesda releasing a game requiring a specific driver for a shit game, and not having the driver until the day before. What could go wrong? AMD drivers are fine. Nvidia loyalists would have you believe otherwise. Me? I'm pretty neutral, I think both have pluses and minuses. AMD has better options that work in CCC, and whatever options you choose for IQ work. AMD lets you do what you want to do IQ wise. If you want SSAA, you can have it. With nvidia CP, you don't get the option for SSAA (unless you use nvidia inspector) -- instead you only get SS transparency which isn't the same. Nvidia "override" option for image quality doesn't work for roughly 65% of games, nvidia freely admits this. You usually have to do some bullcrap in nvidia inspector to force it to work, and even then its not guaranteed - nvidia CP will not enable the override setting you want and won't let you know. Its pretty annoying that "override" doesn't work for many games, unless they're especially old. However, their game profiles applet is far superior to the one found in CCC. And force vsync always works in nvidia CP while it doesn't always for CCC.
Either way, no drivers issues here with either card, ever.
