Before advising please be aware he is asking about s1150 processor, not the s2011 4930k :P
This. 3D guys advising on hardware, always top :- )
4790 is higher clocker
4770, regular Haswell (1150).
Your choice is between Asus (or Gigabyte, but why would your right ;- ) ?) Z97 (Pro) or Hero Maximus (waste of money).
Or you can wait for September, and buy 5820k (LGA 2011-3 /X99 chipset) in similar price range (bit higher 300 euros, but 6core@3.3Ghz baseclock).
