Quad core with two different GPUs? I'm not sure even Lucid will work with that.
don't recall how Lucid's technology worked. I think the only reviews I saw on it was comparing its Hydra technology with NVidia's SLI and AMD's XFire, and 1 discussing the use of its Virtu to combine discrete and integrated.
Its... possible, nearly impossible, but possible. I wouldn't try it though, its too dangerous.
