I was thinking of Mark and his awesome career of getting take photos at live performances but I think there there are a few other heavy Photoshop users on the board too.

A GPU specifically for Photoshop.

I have no idea if it's a worthy investment as my Photoshop experience is limited to a few tweaks of our snapshots. Thought it might be of interest to 'the pros'.

Your link doesn't work, but I'm guessing it's about this product:

Nvidia Quadro CX

It's important to note that the latest version of Photoshop (CS4) takes advantage of most modern GPUs. This product is just specifically tailored to Photoshop and comes with a plug-in that tells Photoshop how to make the most of it.

Thanks. It was. Apparently I cut and pasted the Axiom page link instead of the Engadget one. Kind of an endless loop scenario.
