    I have an early 2005 G5, dual 2.5, 20" Cinema Screen, OS X 10.4.11, with an ATI Radeon 9600 XT AGP card. I discovered (should have known, I guess) that Photoshop CS4's new GPU accelerated features are not supported by this card. Adobe's tech notes say "For Photoshop to access the GPU, your display card must contain a GPU that supports OpenGL and has enough RAM to support Photoshop functions--at least 128 MB of RAM--and a display driver that supports OpenGL 2.0 and Shader Model 3.0.

    I'd appreciate a few video card recommendations. I'd rather not buy a top-of-the-line card, since I may upgrade to a new system in a year or so. Links would be great!

    Thanks for your help!

    Not worth the money if you're buying a new machine. Not to mention even if you find a X800 you're not getting Shader Model 3.0 support.

    I believe the AGP GeForce 6800 upgrade that was once offered by Apple has 3.0 support.

    But one might be difficult to find and expensive as a result.

    Maybe you could look into flashing a PC-compatible 6800 to work on your Mac?

    I have a G5 with the xt800 card.

    Eidorian mentioned above that it will not support Shader Model 3.0 for CS4. What does this mean for useability of CS4; do I lose much of the functionality of Photoshop, or just a few of the image type zooming and panning features, but the rest of the program remains usuable?

    If there are any G5 users that have been using CS4, especially with Tiger - what are your impressions of performance? Is it faster than CS2?

    Thanks for your consideration.

    I almost forgot that you can find flashed AGP 7800GTs on eBay from time to time.

    Yeah a flashed 7800 is the best card you can get.
