I tink SLI does not work with Octane

Would it be better off to just go with a Single 580 w/ 3G of Ram then?

SLI doesn't work in octane, but 2 GPUs give you 2x render times, since Octane is almost linear now (you just don't set them as SLI) the 590 shares the 3Gb between both processors hence having 1,5 each (you can only use the minimun vram common to both cards) so for almost the same price the 570s have almost the same cores and more vram, so I would go for those, if your budget allows it, but that's just my opinion
