GPU not recognised in Guiminer

[LucioMaximo]

Hi, spent about 3 hours looking for solutions to no avail. I am running latest drivers on a gtx 680 4gb, with open cl support,
 but still only get the option under guiminer to use my I7 as the device.


Anybody know a solution?


cheers

I read somewhere that NVIDIA cards aren't the best type suited for mining, but reading my guiminer readme.txt:

For AMD/ATI cards, to get a version of OpenCL you need the Stream SDK which is
available here:
    http://developer.amd.com/tools/heterogeneous-computing/amd-accelerated-parallel-processing-app-sdk/
   
For NVIDIA cards, you can also install OpenCL and mine that way, or you can
install CUDA and use rpcminer-CUDA which may provide slightly higher performance
since it is optimized specifically for NVIDIA cards.

I also have something called GPU_Caps_Viewer_1.18.0 which shows a good breakdown of your system's GPU capabilities - maybe you can spot what's missing with that tool.

Yeah I did all that  already, but it didn't work
