It should work fine with the BitMinter miner (assuming the Nvidia drivers are ok).

There isn't much support for Nvidia cards, especially with the GTX 680.  But a member did compile a small miner to test out:

I have tried to recompile the Ufa-miner and the rpcminer-cuda, but for various reasons it didn't work.
Now I have written a very simple miner using the latest CUDA toolkit, just to see what the speed is like.
Since I have written the kernel from scratch, and the program is not doing longpolling, there's some room for improvement.

If somebody with a GTX680 would like to try it you can download it there:
http://www.sonstiges.org/bitcoin/ICU-Miner.zip
Usage:
Code:
ICU-Miner.exe URL username password devicenumber gridsize blocksize
(devicenumber, gridsize and blocksize are optional)
For example:
Code:
ICU-Miner.exe http://mining.eligius.st:8337/ 1BtVLjUkAzF9wZGHfKzzsPivgNAn4DTp1Q joshua

Here's the ugly source code:

thank you for the information.
I downloaded icu-miner and make it run, I also got ~96MHZ/s, and about 200W power consumption(~90w when idle)

Unfortunately it didn't do as well as we had hoped.  The most I was able to get out of it was ~94 Mh/s.

This is nothing new, the first reviews shows a very poor CL Performance.

The CL Performance is much more lower than the 580.
