Photoshop :: Can't See Photos Opened With CS6?

I just bought a new Toshiba Satellite P855-335 laptop running Windows 8 with a Nvidia GeForce GT 640M video card, but I am only able to open my photos when I disable the Graphics Processor from within CS6 Preferences.  When the check is active,

I see a black screen and the photo is shown only in the Navigator. Is really anoying to have a useles yet powerful video card for my photo editing. My guess is that I am still able to work with my photos because the integrated intel HDGraphics400 video card jumps in when I disable the GPU within photoshop.  
 
What I have done so far:
 
1.- Updated to the latest driver for my set up.  I went to Toshiba website and latest driver was already active. Version 305.46 dated July 2012
2.- I called Nvidia and tried unsuccesfully to install a newer driver (310.90) because is not compatible with my card, they also suggested to install an older driver 304.709 but the operating system just did not want to update to an older driver
3.- I went to Photoshop and followed instructions and none seemed to work: 
3.1. made sure I had latest version of Photoshop CS6 Extended version 13.0.1 x64
3.2.- Set GPU settings to basic
3.3. Reset preferences (Crt+shift+alt) while starting photoshop
3.4. Checked Cache levels to 4
 
Maybe the biggest and unacceptable issue is that the reported NIvidia cards tested with Photosho CS6 doesnt include the 600 Series. It is quite annoying because all the other series are reported: nVidia GeForce 8000, 9000, 100, 200, 300, 400, 500 series
 
My system info reported within photoshop is the following:
 
Adobe Photoshop Version: 13.0.1 (13.0.1 20120808.r.519 2012/08/08:21:00:00) x64
