I've owned a lot of NVidia and Radeon cards. Mostly, they have all been good. What causes me to pick NVidia these days is that some of them take less power than comparable Radeons and, in the past (not necessarily that recent), I liked the antialiasing effect on NVidia cards more than Radeon. In the more-recent past, I didn't like the Radeon driver software that much, but that was still a while back. I haven't tried Radeons in the past several years, and all of this stuff fluctuates over time, so I wouldn't expect those older impressions to last. Overall, I think that people are probably going to be happy with either one, NVidia or Radeon, and that they are very competitive with each other.
