So I'm looking at purchasing an nVidia card (I'm fed up of ATi and their lack of skill when it comes to drivers). I've not used nVidia for almost 7 years now, and I'm wondering how people rate the various card manufacturers. I've been eyeing up MSI, Gainward and Zotac. Should I be considering any others? Zotac seem quite good, and they offer a 5 year warranty.
