I've only had problems with them recently. The motherboard issues plus the driver problems I've been having plus their amazingly pitiful support for these huge issues is what turned me off. There's thousands of people who have faulty nForce 7 (not just 750i owners like myself, but also the high end 780 and 790 owners) chips that are just as screwed as I am and nVIDIA doesn't seem to give a damn.
So, fuck 'em. I'll stick with ATI video cards and Intel chipsets until I have a reason to go back.
