Few odd OpenGL Nvidia options. Any ideas?

[Glow]

I have these listed for my Geforce 4 4200. So lemme know what you guys would put for these.
Disable support for enhanced CPU instruction sets. [yes or no]
Enable conformant OpenGL texture clamp behavior. [yes or no]
Buffer flipping mode. Use block transfer?

Disable support for enhanced CPU instruction sets. [no]

If you disable this, the driver won't use SSE or other similar instructions, this will slow down the video card.

Enable conformant OpenGL texture clamp behavior. [no]

Not sure what this does, but I everything I have read says to leave this off.

Buffer flipping mode. Use block transfer? [Yes or Auto]

Block is faster than Page, but I think some applications, prefer Page flip.
