Photoshop CS6 opens quickly- must wait 2-3 minutes to use program.

Question

Greetings.  New to the forum.  I've found several references to my problem online, but none of the suggestions seems to work.  I have a brand new iMac running 10.9.4 Mavericks.  It has a 2.7 GHz Intel Core i5 processor and 16 GB of RAM.  I also have the 1TB Fusion Hard Drive.
When I open Photoshop it snaps open almost immediately.  If I click on a photo file and "open with" Photo shop, photoshop snaps open almost immediately and the photo opens about as quickly.  BUT... then I get the spinning beach ball for anywhere from 2-3 minutes before I can actually use the program.  Before I updated CS6 today, Photoshop would open and hang for 2-4 minutes on the "measuring memory" message.  Sometimes it would open, sometimes it would not open.  I just got CS6 today- and yes, it's a legal copy with valid serial number purchased from the university.
I've tried a few other programs in the suite (Premiere, Encore, Illustrator...and gave up waiting for them to load.  I've tried changing the performance settings in Photoshop.  I've deleted bad fonts.  I unchecked the "use graphics processor."  I've made sure that Photoshop can get through the iMac firewall.
Once the program finally loads, I can work with it and it seems "normal."  Ive have CS6 on my work iMac and it is very fast- but that machine is running Mountain Lion.
Any suggestions would be appreciated.

thanks for your reply.
This is because PS turned off the GPU when I opened it in safe mode.
When I can access PS normally, both cards are recognised:

is uninstalling the graphics card the only fix for this? I'm reluctant to try this, and cause more problems..
