I had an nvidia card in my possession briefly recently. when I was testing it I found distros that have a separate nvidia installer image are the way to go if you dont want to have a shit time. Converting a standard image post install is about as much of a shit task as it was back when I had a gtx 460. once its set up either way it seems mostly fine but I already had a more recent amd card and don't want to deal with the kernel module crap. dkms has failed me a few times in the old days and I never forgave it.
