Take a look at the Cinebench results.
You can see that the 2600k at only 4.3ghz, can easily match the 3.3ghz 6 core 980x.
Cinebench is one of the few tests I take seriously, because it is a rendering app that actually makes use of all cores available, and scales well with HT.
It should be noted, that 4.3ghz is nothing for the 2600k, while for the 980x, it is actually close to max OC.
Consider the fact that SB can do 5ghz on air, and it should easily match an overclocked 980x.
That's why I say AMD will have trouble competing with SB.
And 5Ghz isn't really an average max clock for SB... I've seen people struggling to get past 4.6 without excessive volts.
