    There are instances where card passes Furmark, but fails other tests (including actual games).

    So a failing card, thermally stressed to the max, will pass a Furmark (and similar) tortures?

    That's because Furmark unevenly over-stresses the GPU. Some of the GPU's functions are left practically untouched. Aside from that, newer versions of VGA drivers recognize Furmark (either by .exe name or by heuristics/behavior) and throttle the GPU as a countermeasure.

    Unigine tech demos (Haven, Valley) and other 3D benchmark tools are better suited for testing. So is (prolonged) regular gaming.
    Careful what you wish for... You just might get it.

    Last night I ran 3DMark Sky Diver twice and Fire Strike once. I then proceed playing Far Cry 3 over 2 hours. Seems fine enough I guess

    This, and also AFAIK Furmark stresses pretty much only the GPU core, not the memory.

    I'd suggest using an app/game that heavily utilises DirectX11 features. Eg. Crysis 2 w/Dx11 enabled is regarded to be a decent way of testing stability.
