Do Adobe Photoshop CS5 and Adobe Premiere CS5 use the GPU? Does the choice of the graphic card change the performance of these programs?

-1 Can be answered using the Wikipedia article (title of one of the references, to be exact, took me all of two minutes), i.e. question does not show any research effort. –  Daniel Beck Sep 23 '11 at 20:29
    
I totally disagree with the closed as too localized. Type into google does photoshop use and you get my question. –  pinouchon Sep 24 '11 at 17:21
    
I get this and this when searching does photoshop use gpu. // You can always flag your question for moderator attention and petition to reopen, giving your reasons. I don't understand the reason to close either, even if I consider this to not be a good question. Maybe a comment by @random would be helpful here. –  Daniel Beck Sep 24 '11 at 17:33
    
With that said, I agree that this is easily answered. So I don't mind if the question gets downvoted. I am just against the closing. –  pinouchon Sep 24 '11 at 19:18

According to Adobe:

Photoshop CS5 and CS4 leverage the video adapter's chip (the graphics 
processing unit, or GPU) instead of the computer's main chip (CPU) to speed 
some functions. Photoshop accesses and uses the GPU when the GPU:

- supports OpenGL, a software and hardware standard that accelerates video 
processing when working with large or complex images, including 3D.
- has at least 256 MB of RAM.
- has a display driver that supports OpenGL 2.0 and Shader Model 3.0, 
which the GPU uses to perform rendering effects.

So yes, your choice of graphics card will quite likely affect how well Photoshop will perform. Newer higher performance cards will likely give better performance.

Yes. The amount of gpu would depend on what kind or how much editing you are doing.
