I just purchased an HP h8-1080t system (64 bit, 16GB RAM) and a bunch of other bells & whistles. I selected the AMD Radeon HD 6670 GPU with 1024MB DDR5 RAM.

I use it primarily for photographic editing in Adobe Photoshop CS5.1 and need OpenGL support. I also use DxOLabs software that uses OpenCL. My card has both.

Since then I started sharing my computer with BONIC by letting it run scientific calculations whenever the system is idle. One of the applications is MilkyWay@Home. another is SETI@Home. There have not been any issues except for some of the MilkyWay@Home calculations an ATI GPU that supports double precision math is required.

Does anybody have any advice on which card has at least 1GB RAM, OpenGL and OpenCL support and the double precision math capability? I did not mention that I also need DVI and HDMI output for multiple monitors.

I would sure welcome recommendations as the subject in detail is new to me and I get confused trying to sort through all of the details.
