Display Adapter Recommendation?

I currently have a Sony CDP-G400 and a Hitachi SuperScan Elite 751 (both 19") hooked up to a Matrox G450 dual-head adapter. I just purchased the Monaco Optix XR-Pro bundle, and need to move to two separate adpaters to calibrate each monitor individually.

I’m not a gamer so I know I don’t need one of the high-power cards being sold for that market. I do mostly digital photography and editing with
Photoshop CS2. Is there a “recommended” display adapter that works best
in this space?
