I think I already gave you every informations you need. (How to access and use the factory menu, what are my recommendations...) You should try to start it alone and ask specific questions when you lose the control over the process. (You should wait for the new ArgyllCMS bugfix release. But, of course, you can start to discover the functions now. I am currently using my display with a LUT which I created with this buggy version, it is not useless.) 8600GT works with effectively 8 bit/color LUT and framebuffers. sRGB is better choice for generic PC usage (end-user softwares, web surfing, movie watching, PC gaming, etc.) and Standard is better for advanced usage (photo editing, picture viewer and movie player softwares with high quality color management features, etc).
