This looks like bad new for me. I am upgrading to a 780i and Vista 64 in about 2 weeks. Shortly after that I planned to get a second GTS for SLI. Maybe I will have to rethink that!
No settings on the bios. It all in the OS. If getting Vista make sure you install all the hotfixes. I had mine working fine with Vista but it was too much work. Its very simple to get it to work in XP.
