Sorry for the delay but had errands this evening while trying to also sit and benchmark lots of stuff.
Apparently Kuro is indeed correct in his results. I figure stuff simply is not optimized for it just yet or that there must be some difference in how the 680 utilizes CUDA compared to the 580.
Since I'm no command line expert, I just did the following:
1. Launch GUIMiner (my version was 2011-8-24) which I'd normally use just fine. Tried the same settings for my 680 that worked with my 580. Nothing.
2. Updated GUIMiner to the latest I think (2012-2-19) and tried the settings again. Nothing.
3. Started launching miners by attempting each of the miner options.
OpenCL = Works but might blank the display. Crashed the system once I stopped it but did get mining results. System seemed stable while mining.
Phoenix = Launched but sat at "Connection Problems" No luck despite being configured correctly.
CG = Same as above.
CUDA = Same as above.
Ufasoft = Same as above but without any "Connection Problems" at all. Start mining button did nothing.
Other Miner .. not sure what to try here.
Results with the one or two miners I tried (forgot to name the tab so Phoenix may work as well as OpenCL):

Indeed, we're at ~110MH/sec. This is stock w/GPU boost. I have not yet attempted to even mess with power boosting and overclocking the card but either way it doesn't really matter at this point in time.
Here's hoping that a proper update to things will eventually happen! Thanks for the patience everyone. As far as games go outside of BTC mining, this card rocks. But alas, that's not why we're here. I'm sure once some optimizations are made, it might work better.
Drivers are the Nvidia 301.10 launch (only ones so far) and running Windows 7 x64.
