High end graphics card for Photoshop?

So a photographer friend of mine was curious if getting a better graphics card would translate into faster Photoshop.  Ordinarily I wouldn't think so, but Apple has been trying to play up the fact that its handing off more and more to the video card and Photoshop has advertised increasing integration with the OS.  This is why I was confused about the issue.  Turns out its all smoke and mirrors.

A brief look into this shows this doesn't mean jack when it comes to Photoshop.  Unless its an Intel graphics card or a no-name company listed as "on board," definitely go with a basic graphics card.  In my case, my friend was only going to buy a Mac and they don't even sell "on board" video cards anymore.  Power on the graphics card doesn't translate into Photoshop power.
