that card won't work, your monitor won't work...

Where do I start...

The Radeon card you're looking at won't work.

In order to get 10 bit per channel color with newer versions of Photoshop, you'll need an AMD FirePro card or Nvidia Quadro card.

That's because the drivers are not going to allow 10 bit per channel color with apps like Photoshop unless you're using a Pro level card (either a newer AMD FirePro model or newer Nvidia Quadro Model), even if the cards you're looking at have a DisplayPort.

IOW, AMD and Nvidia don't provide drivers allowing a 10 bit per channel color pipeline with apps like Photoshop unless you move to a Pro level card (AMD FirePro model or Nvidia Quadro model; versus one of the AMD Radeon models or Nvidia GeForce Models).

But your existing HP display is not capable of 10 bit per channel color either.

If you wanted to move into a newer Nvidia Quadro Card or AMD FirePro card with a Displayport, *and* you bought a display capable of 10 bit per channel color; then you could get that feature with *some* applications.

With CS5, support was marginal for that feature (10 bit per channel, a.k.a., 30 bit color); and you'd be better off sticking with using a FirePro versus Quadro Card to have a better chance if it working OK.

With CS6, you should be able to get Nvidia Quadro cards working with 10 bit per channel color, too.

But, forget using consumer level cards (Nvidia GeForce or AMD Radeon cards), as they're not going to allow 10 bit per channel color with Photoshop.  You'll need a Pro level card (Nvidia Quadro or AMD FirePro) with a DisplayPort and monitor capable of 10 bits per channel to get that feature.

Also note that Lightroom isn't going to support 10 bit per channel color, period.  Very few applications will.  CS6 will (provided you're using an Nvidia Quadro Card or AMD FirePro Card with the correct drivers).  But, most applications will not allow 10 bit per channel color (and that includes the actual Windows desktop, as it's only capable of 8 bits per channel).

Personally, I wouldn't go to that much trouble, just to get 10 bit per channel color support in Photoshop (buying a Pro level Quadro or FirePro card, monitor that supports it, etc.), especially since the *only* place you're going to see any difference is while working in Photoshop, as the output is going to be the same, even without that support.    So, why go to a lot of extra trouble just to see 10 bit while editing in very few apps that support it (and again, Lightroom doesn't support 10 bits per channel either).

But, some people want that feature.
