I've been using Ubuntu on my main PC for a while now, starting with the 7.04 release. Back then it seemed a real advantage for me to have the nVidia 6800GT I have rather than a friend who had an ATI 9600XT. At the time the support for nVidia seemed much better. Is that the case now? I'm about to upgrade my rig and will need a new video card (I'm still on AGP), not sure what to do though. I was thinking of something like a 7800/7900 series nVidia but it seems I may get similar performance for cheaper with ATI/AMD cards.. in Windows at least. So is ATI/AMD easy to get working to proper standards in Linux, Ubuntu specifically. Love to get some feedback from people who have both setups running.
