Got CUDA 5.0.37 installed, but still dont see any options to choose CUDA in the preferences. I tried 2.63, 2.64 and the latest daily build... none displays any option to use CUDA or GPU. Seems that Im not the only one to experience that issue.

I have the same problem with this card on Blender 2.64a... if i use CPU and not GPU Compute, textures are ok when rendering and also on the 3D viewport but if i change to GPU Compute, textures are gone!!! all the textures change like no material!!!!
Are there any step or configuration on Blender to change this situation? or is there any other option that i need to choose on node editor?

Thanks in advance.
