Funny how some people forget about the famous driver issues with Nvidia over the years.

So many people living in the past and so many rose tinted glasses users in here
Either that or certain people don't know how to install drivers correctly and/or operate a computer correctly or they just want to clutch to their very last straw 
Been with AMD since the 4850 and not had any serious issues, biggest issue, which "might" have been down to AMD... was when I got my 290, my PC was incredibly unstable, no idea if it was the 290 and/or AMD drivers in the end as the problem just seemed to solve itself.
As for games, only one game in all this time that I can recall of having an issue with, which has been directly because of AMD and that is battlefront and missing textures on certain maps, they did take a good few weeks to fix it... Any other issues have either been down to the game or/and something else on my PC acting up.
Over the last 1-2 years, I would say that AMD have had the more stable drivers than nvidia if forums like these are anything to go by... The countless hot fixes nvida release to fix problems in their supposedly latest stable driver is hilarious and then all the comments of "rolled back, all good again" is shockingly high, iirc, the likes of neil79 etc. are sticking to the developer drivers as they find them to be the most stable.
Saying that, AMD's latest relive drivers have been shocking for me (not too surprising given how many new features and under the hood changes they contain) but hey, you can always "roll back"...
