I'm so lost, and confused. I don't want to give up and go Intel, not now at least!

I still don't really know what's going on. Try updating to the latest beta drivers that just came out (285.79). Also, after doing that, try installing the um. NVIDIA System Tools (6.06). That's all I can think of.
SLI might not be registering because it might think your GPUs are mismatched. I have no idea why the SLI menu isn't even showing up, though. When you install the 285.79, go into advanced/custom installation, click do a clean install, and also make sure all the installation boxes are checked.
