Let's compare some of the stats:
nVIDIA clock speed: 270MHz
Radeon clock speed: 380MHz
nVIDIA memory speed: 400MHz
Radeon memory speed: 680MHz
DirectX 9 support with nVIDIA: Yes
DirectX 9 support with Radeon: Yes
OpenGL 2.0 support with nVIDIA: No (1.4 instead)
OpenGL 2.0 support with Radeon: Yes
My inclination is to say yes just looking at the speeds, but I do not have any real-world performance data to draw on. I also figure the Radeon would stay in my rig longer before needing to be replaced.
So what say you?
