Most cards can do in the +150MHz to +200MHz range. But of course there is no way to say exactly what frequency this is because there are many variables. Power, heat and app all play a role.
This means comparing an overclocked 7970 with no voltage boost against a 680 overclocked is BS?
In that case, 7970 @ 1250/1600 vs 680 @ ~1250/1600 is a quite valid comparison.

I wonder when they're going to take this ticker down?
Nvidia needs to release drivers to properly support 3 & 4 way SLI.
Guru3D doesn't update scores with new drivers, the 6990 scores about P10000 i 3DMark11 at stock.
The 6990 scores exactly the same in it's launch review as the 680 SLI review that's almost 12 months later.
The driver scaling for three- and four-way SLI is broken, so for now it's only interesting where quadSLI scales "okayish". It's more interesting to note that 680 SLI only scales ~180% when we're not looking at a clear-cut CPU bottleneck.

i7-965 @ 3.75GHz

I'm not sure what is going on with 680 overclock scaling.... It doesn't see to budge more than 2-3 fps in all of these tests with 150+ mhz overclocks.
He doesn't overclock the memory, while the 7970 probably has a lot of "spare" bandwidth, the 680 is probably being bottlenecked by it's 192GB/s. Or maybe it's a CPU bottleneck.
