You need to edit the "cuda_supported_cards.txt" file.
Add in your card and save the file. (make a backup for safety)
Yes, your NVIDIA GeForce GT650M should be suported.
features added or changed in this update
- Windows 8 certification
- updates for HiDPI display, which improves appearance on computers that use Retina Display, such as MacBook Pro computers
- added GPUs to the list of those that Premiere Pro CS6 will use for GPU processing: GT 650M (which is in the newer MacBook Pro computers) and GTX 680Note: Premiere Pro can use either OpenCL or CUDA for GPU processing on the GT 650M. The default is to use OpenCL. You can change this in the General project settings.For details of GPU acceleration in Premiere Pro, see this page. For details of OpenCL features in Premiere Pro CS6, see this page.
Here you could activate your Graphic Card and enable the Mercury Playback Engine and GPU acceleration to take full advantage of the CUDA or OpenCL technology.
The thing abotu this is that it only gives you the OpenCL option, right? I'm having issues with files that were rendered in CUDA not working in my MBP Retina with OpenCL, it either won't open or won't play. Unfortunately I don't see any other option that OpenCL and Software Only.
That explanation doesn't make sense. A file exported out of PP using CUDA will not be materially different than a file exported out using software mode.
Some other explanation is likely the cause of your playback troubles.

Mi MBP does't came with a Nvidia(CUDA)card, instead it came with AMD Radeon (HD 6770M 1040 MB, Open CL) that's why I only have two options, Software only and OpenCL.
There's a discussion and debate right now on the forums and the web about a lot of people having problems with the Graphics cards and Open CL and specially with CUDA technology. You should be aware, if not all ready, before proceeding with this.
