In addition to Jacob's comment and suggestion, since Photoshop is the most intensive program, relating to the GPU, I think that I would ask to have your post Moved to the Photoshop>General Discussions Forum.
If you like, I can Move it for you. Just click on my Profile, and choose Send Private Message, as I do not want to Move it, if you have already posted there - duplicate posts are confusing, and discouraged. Just let me know.
Now, one problem that I see with the embedded Intel GPU chip is the lack of video driver support. PS requires a deep interface with the video driver. For that reason, I suggest nVidia, or AMD/ATI, as they have much, much better driver support. I think that you will hear similar in either the Creative Suite, or Photoshop Forum.

Photoshop was chosen because it is the most intensive program in the OP's suite.
Intel's drivers have some problems, but they have been improving them and released several updates recently to fix outstanding bugs.
My system runs the Intel 4000 and quite pleased with it. There have been a few recent upgrades which have fixed a few minor problems - but the fixes are aimed at games not our sort of editing. That said, my experience is very positive, no real issues and I do some pretty intensive work in both Photoshop, Lightroom and a few other graphic/photographic packages. I run Photoshop CS5 and CS6.
Hope this helps
