I have used both. Someone had told me that ATi was the way to go, so that was the first card I had ever purchased for my newly built computer. I ended up having the same issues beedubaya has with his card and I am now happy with my nVidia video card
DJ-CHRIS, neither suck, and the faster they rush the cards, then the least amount of time we have to wait for better technology. Both Brands do a great job.
