ratGPU OpenCL raytracing benchmark

The option to use both the cpu and gpu won't show.

Well, you should see ratGPU c++ device always. That's kinda strange
If you could not see the AMD Stream: CPU device could be logical as you're using an NVIDIA card but the C++ dev should be always present ( unless your Athlon II is OCd but not stable so the system could start making strange things )
