making a processor decision

Solution
I'd jump on the 6700k. The single-threaded performance difference between it and the 5820k isn't close, really, and the 6700k doesn't lag too far behind the 5820k in multi-threaded benchmarks. Source: http://www.tomshardware.com/reviews/skylake-intel-core-i7-6700k-core-i5-6600k,4252-7.html

I wouldn't buy the 4790k just because it's an older platform while the 6700k is brand new. Add to that the jump to DDR4 Ram that Skylake and beyond ushers in and the 4790k is a dead end overall.
I vote for the i7-6700K.
Games depend on a few fast cores.
The 5820K has a single core rating of 2001, the 6700K is 2283. More with overclocking.

For cpu bound multithreaded apps, the 6 core might be better.
But it is easier to tolerate slightly longer batch run times for rendering and such than it is to tolerate hiccups while gaming.

For multitasking, just buy sufficient ram to concurrently hold all the active tasks.
 
if i decide to stream id have my game on one monitor and obs on the other. and btw a single core score isnt going to matter because the 5820k has 6 cores and the 6700k has 4 so ultimatley the 5820k has a better score.
 


Not exactly.
Most games are not truly multithreaded.
They depend on a single fast master core to distribute work to secondary threads.

Read up on "Amdahl's law" for more.

1, that's Wikipedia. Never trust Wikipedia, and 2, idk about this site because sometimes I think "jeez this is a bunch of plagerised information." Now what's the difference performance wide between the i7 4790k and the i7 6700k
