I would rule out the 690 the AMD Radeon 7970 6GB OC special edition versions for two reasons, firstly very few people will use these card, so it won't be used to test software making you more likely to experience issues with it, secondly they are poor value for money. AMD and NVidia will presumably update their FirePro and Quadro series GPUs sometime in the next year, save the money in case it is a must have update!
The compute functions in NVidia consumer cards are intentionally crippled, they want you to buy a Quadro!
Vue 10.5 does not use the GPU for rendering, with the possible exception of some use for Anti-aliasing. Vue also does not do computations on the GPU in the current release, it only uses OpenGL for the viewport display, so the CUDA OpenCL arguments are irrelevent for Vue. You don't say what other 3D applications you are using, or plan to use, so that may be a factor to consider.
You are probably aware that e-on software have a list of suggested GPUs, you can find this here:

For cards not on this list you should ask e-on software directly.
Regarding the use of GPU processing in Adobe CS6, the information you quote is not quite correct. For AMD cards Adobe CS6 uses OpenCL, for NVidia cards CUDA, there is a very short list of functions where GPU processing is only available on CUDA not on OpenCL. See this link for details.

Personnally, as OpenCL is an open standard, and CUDA is proprietary to NVidia, I would prefer to see OpenCL implementations over CUDA.
For people who spend most or all of their time working with a single applicaiton like Maya, or Houdini, it makes sense to research the best GPU for the app and invest money there rather than in higher performance CPUs. However, for users that are working accross many different applications it may make sense to spend more of the budget on the CPU, which will benefit all applicaitons rather than the GPU, which may only benefit specific apps.
Finally, I find the whole GPU thing is very complex and not at all transparent. You usually can pick sets of benchmarks that favour whatever card you want to favour! I would rather invest money in CPU, where it is easy to see what you are getting, than GPU where you may or may not see any improvements in performance.
