Hesitating between CPUs

Hey guys !
I've been looking to build a new gaming computer, and I'm trying to get to high performances without looking too much at the price (though obviously still caring about differences of over a hundred dollars) Current goal is to be able to play The Witcher 3 at max when it comes out, and run previous games, such as Crysis 3 or Metro: Last Light just as well.
Obviously I've been looking for a powerful enough CPU, but I'm still unable to make my mind... Right now I'm finding the i7 4820k quite to my taste, with pretty solid stats and very favorable reviews, which would make me pick it over the 4770k, because I read it has cooling issues. However, I've also been considering the 4930k, which also seems to reportedly have very few issues and hovers around the same speeds as the 4820, but obviously the 2 extra cores and the slightly better cache make it 250$ more expensive (at least on newegg).
Right now, it feels like a hex-core may not make that much of a difference and the 75% increase in price is pretty massive to me. Would you agree with me assuming that a 4820 would do almost as well at the moment, and that its (albeit certainly small) decreasing effectiveness compared to a 4930 in the long run would be compensated by the spared bucks ?
Thank you for your answers !
 
Solution
4820k will do just great, we are talking maybe 2-5 FPS difference and slightly worse physics computing. I have it's little brother the 3820. Also remember that 3820, 4820k and the 4930k use quad channel membus. I'm thinking of upgrading to the 4820k, but my gains would be negligible at best! Maybe a slightly faster RAMdisk performance due to the better mem controller, and 5-10% better physics performance. xD

Solution
A 4790k has a faster core speed and is more energy efficient, but the 4820k benefits from more PCI-E lane compatibility. You can keep a 4790k cool with a performance CPU fan or liquid cooler and that would be a cheaper option. Because of the higher clock speeds, the 4790k would actually perform better in gaming benchmarks. But for serious video rendering, CAD, etc., the LGA 2011 platform is the way to go.

Thank you all for your feedback ! I hadn't really taken the smaller details into account, but I do think I will stick with a LGA 2011 instead of a 1150, thus choosing the 4820k over the 4790k (and the 4770k for that matter). I'm also not feeling waiting a few more months just for a lower priced hex-core :p At least I know that in a few years when I'll be looking to change my CPU, I'll have cheaper options ^_^
