Displaying CUDA 2D data The process of moving CUDA data onto a texture or similar

I know this has been asked before but I have yet to find a definitive answer to the best way of doing the following: displaying the contents of some cuda 2d data as a texture or whatever in OpenGL. My current process is this:

  1. Create some cuda data, right now of the cudaMemset2D kind (normal array but padded)
  2. Copy data to PBO of the same size as the texture.
  3. Copy data via GL_PIXEL_UNPACK_BUFFER_ARB to a texture.
  4. Use texture and draw with standard GL_QUADS.

Is there some nice way to avoid using a PBO and move the data directly on to the texture? This extra step is a pretty costly procedure.
