ATI OpenGL questions

[no2censorship]

1. Should I have any IQ, artifact, stability, or compatibility issues on my iceq4 1GB HD4850 with ANY opengl games (with 8.10 drivers) that I wouldn't on an 8800GT (I'm asking b/c I'm ditching it)? MDK 2 seemed to work great, but that's the only opengl game i've tried so far.

2. Why are nvidia's opengl drivers said to be better than ATI's other than in terms of performance (that is, if nvidia has other opengl advantages beside performance)?

3. Why doesn't ati have the conformant texture clamp and gl ext limit options like nvidia does?

Try to answer any you know the answers to ASAP=]

Thanks in advance=]

1) None that I know of. I haven't had any issues with my 4850 and OpenGL games in Vista and Ubuntu x64

2) Neither camp's OpenGL is better than the others as far as I know. The performance in OpenGL generally lines up with DirectX games (as in, if a card is faster in most directx games, it'll be faster in most opengl games as well)

3) No idea. Why didn't Nvidia add DirectX 10.1 support to the GTX 2xx series? Nobody knows
