    I just installed an ATI 5770 in a 2008 8-core MacPro and was expecting at least some speed improvement over my existing 2600XT. I had read online that Aperture 3 used OpenCL, which is supposed to supported by the 5770.

    When I didn't see much improvement, I started up atMonitor to see if I can see any GPU% activity. Nothing. Flatline. Does anyone know if atMonitor supports showing GPU activity with this card?

    What exactly are you testing? I think Aperture only supports OpenCL for exporting files.

    Actually I read that Aperture uses OpenGL and I don't think anyone knows exactly for what.

    Good info here...

    Import a few hundred RAW files using Aperture 3. Then export the versions. Lift and stamp 200 pictures. Render out a DVD using iDVD.

    GPU shows 0% for all of the above. CPU, RAM and VRAM all climb up. I'm wondering if atMonitor just doesn't support the 5770?
