These are the rumored clocks quoted by most websites, but nothing's set on stone until cards hit the market.
Anyway, I don't think there's gonna be much headroom for OCing, as two GF110s on a single PCB may already be pushing both the thermal dissipation and PCIe spec power limits at these clocks...
GTX590 clocks:

GTX580 SLI clocks:

The scores are aprox. 19% appart, almost the same ratio as the Vantage scores...
Was just trying to help ppl get a glimpse of what the GTX590 performance may be based on readily available GTX580 SLI benchmarks by giving an aproximate percentage factor, this may give you a vague idea of what to expect based on a single synthetic benchmark, of course, gaming performance may be another story.
It's not about the "f*cked up" scores as you mention, your comment there almost comes off as trolling... :shadedshu
