I wasn't bashing anyone's drivers, just to be clear.
Both don't give me any problems that would stop me buying either, it always goes down to bbfb for me every time.
Same, though it does irk me people insist Nvidia's drivers are better, currently most reviewers seem to flat out agree that SLI is working a lot worse than xfire, Nvidia also has the most current long term big problems like TDR and both companies have a bunch of minor bugs that is expected, craploads of code, thousands of diff software combinations and states, stuff happens, and new features are always going to have teething issues.
Also worth noting AMD haven't created drivers that kills their own hardware, Nvidia have done it, afaik, at least twice.
Currently AMD drivers are better, both for xfire and standard, that doesn't mean a LOT of people won't have a problem with an AMD card that they won't pee them off and if they switch to Nvidia it won't go, that's life, the reverse is also true. Currently, not always, its swings and roundabouts, AMD went through its greyscreen period, which was so easy to fix yourself but few did. At that time Nvidia had less really awkward bugs, but they also had the advantage of seeing the greyscreen issue for AMD and being able to get a fix in before release rather than post release. In a few months Nvidia will finally have fixed TDR and AMD will have something else, rinse repeat.
One thing I do find odd though, average joe looking through this forum because its a multi purpose forum, will see way more AMD problems. For some reason AMD problems get posted on all the big forums, Nvidia guys all seem to go to Nvidia's forums, it somewhat keeps their biggest issues almost... private.
Joe bloggs buying a new gpu might wander onto these forums of the shop he's looking at and have a look at the GPU forum and see all AMD problems, he's unlikely to go on the Nvidia support forums.
To sum up, both companies have problems, probably 99.5% of AMD AND Nvidia owners have no significant problems with drivers, ever. The 0.5% will be 0.1% real problems where AMD/Nvidia screw up, and 0.4% random system incompatibility, bad luck and or failed hardware that people put down to bad drivers.
THe daft thing is, that 0.4% swear blind everywhere they can that whichever company has screwed them over, has the worst drivers ever made for anything and will die hard be a fanboy of one of those companies.
I've never had real problems with Nvidia drivers, and I've never had real problems with AMD drivers, minor bugs with both, minor SLI/xfire annoyances, 99.9% of my gaming with either brand has been smooth sailing.
