GPU for blender, OpenCL vs CUDA

[Mclai]

I'm confused because blenders site recommends Open CL GPU cards, but all the forums talk about how CUDA is necessary for the rendering and that the Open CL is not supported? Which do I go with? Is this a more recent development?

this is not the latest info but it could explain why CUDA is more preferred:
