AMD is pretty good with drivers for single cards, never had a problem in my experiences with their cards. When you get into Crossfire applications though it can be a bit messy, but considering that's a rather small percentage of computer users and the average gamer would never find using dual 7970's to be all that useful for anything other then maximum settings with Eyefinity, however if you are using a single monitor and are running at 1080p resolution you should be able to max out most games settings wise, very few demand more then that.
