Stop being so naive
. Facts being its been done time and time before by both cpu manufacturers and gpu manufacturers, and that its great business sense for intel at the moment (but crap for us consumers hence me making such comment) during amd's competitive absence in this part of the market.
Yes there will be a certain element of defective cpu's of course, and they will get binned accordingly, but with the seemingly large demand for 5820k just from this thread alone, do you really think miracously hundreds and hundreds of thousands of 5820k's will conveniently have manufacture defects allowing perfectly only 1x16, 1x8 and 1x4 pci-e lanes? No. They will be lasering pci-e or whatever process used a large number of '5930k' chips to make the 5820k's. They would never keep up with demand otherwise. Intel modifying chips would greatly outweigh manufacture defects, affecting 'just' the pci-e lanes. Remember: the only difference between 5930k and 5820k are pci-e lanes, they both have 6 cores still.
Other than that you make one good point in your post, in that intel is propping up the market for their 5930k.
As i say, great for intel, not for us consumers. Haters gonna hate moaners gonna moan etc. we need to have a voice for whatever little its worth. I and i suppose many others wouldnt mind so much if we had our pants pulled down sometimes in situations like these with lack of competition, IF it wasnt the case all we have and are getting are incremental increases, larger prices and early superseding of products / overly frequent new sockets and platforms.
