[LAU] non-nVidia 3D graphics ?

[Dave Phillips]

Greetings,

A quick question: Is there any acceptable substitute for nVidia's 
3D-capable chipsets ? I'm particularly interested in hearing from anyone 
who formerly used nVidia hardware and has switched to something of equal 
performance capability, assuming there is such a thing. Also, I'm not 
very interested in what's going to happen, I'm interested in what's 
available now.

Best,
