Practically speaking, what is the difference between the NVIDIA GeForce FX 5200 Ultra and the ATI Radeon 9600 Pro? I have heard a lot of talk about how the former is far inferior to the latter, but on a practical level, where would I see the difference? I am a Web designer with a G5 1.6 GHz, working on dual Apple 17" studio displays. I don't play any games and the primary applications that I use are Photoshop, Illustrator, GoLive, Flash, and the iLife suite. What would I notice were I to upgrade my card from the NVIDIA to the Radeon?
