[opensuse] Best (supported) graphics card

Hello list-mates, Since I am slowly beginning to consider buying a new machine (see another thread), but haven't done so in a while, I am not really up to speed with graphics adapters. My current machine has an NVidia FX5200, which is an okay budget card. But the performance isn't exactly stellar and of course it is quite dated. So what I am looking for is some feedback on which current graphics cards are, in this order of importance: a) best supported under openSUSE/Linux b) have great performance and deliver jaw-dropping graphics :-) c) do not cost an arm and a leg, or my first-born I don't mind so much loading a proprietary driver, but if it can be avoided, that would be nice. Hope to hear some thoughts/experiences. Joop
