It's hard to recommend going for the I7 because of hyperthreading but at least consider it. Performance differences aren't that huge atm and going for more cores instead of HTT is the better option anyway but I have the feeling that the I7 might be able to hold out a bit longer in the future. Still I understand going for another +130ish bugs is significant.
Anyway paying 'just' extra 25-35 bugs to go for higher clocked ddr4 ram seems to be worthwhile, just as a tip.

Thanks. IN the past I always good of with going for middleclass. My i5 was with me since 2011. An i7 would'nt have lasted much longer, I guess. Which clock for the RAM do you suggest?
Oh, one more thing: I just bought this RAM here: Corsair CMY16GX3M2A2400C11R Vengeance Pro Series 16GB (2x8GB) DDR3 2400Mhz CL11 XMP
It would make no sense to keep it for the 6600K, would it, because it's not DDR4?
