Not much.. Tho the 5960X is much cheaper..

I haven't seen too much evidence to indicate that GPUs running PCIe 3.0 x8 suffer measurable performance degradation.
It's a money grab from people that think they have to have the extra lanes, to be sure, but I would not be too concerned about running 2 GPUs with 28 lanes. You can run dual GPUs all day on Z97 with 16 lanes, so 28 is a bonus, and the 5820K is not really all that expensive compared to previous generation hexacores. Certainly with tri- or quad- anything you have to step up, but that's not something too many of us will be worrying about.That's true but this is Intel Enthusiast platform we are talking about. They never previously gimped their X48, X58, or X79 the way they did with X99. Forcing users to buy a $500+ chip instead of the $350 version just to get full SLI / Crossfire is inexcusable in my opinion.

I couldn't bear the thought of buying a 5960X for gaming and not overclocking it! Taking a look at the "Overclocked CPUs" chart at Passmark shows the average "out of spec" 5960X score to be 19029. I am willing to bet that most purposely OCed units would exceed that score, so as has been mentioned, it depends entirely on the willingness to OC.
