    How can I overclock a apple provided Radeon 5870?
    Core clock / mem clock?

    Can it be done in the card bios? What utility can edit the bios?

    THX

    Probably no need to do this in OS X as there appears to be a performance curve on OpenGL from Apple. 5770 scores very close to 5870 so more juice will not really help. I use the Catalyst suite in Win 7 and only go as far as 900MHz core and 1280Mhz Mem. That nets me 1000 more gpu points in Vantage but generally not worth it for actual 3-4 FPS you get. So overclock in Win. Pointless on Mac. IMO anyway.
