I think you should go for a 6+ core CPU for your tasks.
Games will still run fine, but you'll have better performance in "work".
Links, thanks, but how much is the difference in the ''work'' bench between these two? difference in only few minutes?
Also, the i7 7700k has a higher frequency rate, doesn't that ballance the workflow at the end?
There is always a few seconds difference).
You don't compare 7700k with pentium 4, right?)
According to Aida64 CPU Photoworxx test
I7 7700k @ 4,8Ghz is mached with 6850k @ 3,6Ghz.
So you can see, that 4*4,8 = 6*3.6 ( something near)
CPU Queen test shows that 5820k @ 3,3Ghz gets the same score as 7700k @ 4,8Ghz.
But 6850k @ 3,6Ghz (and 4930k @ 3,4Ghz) is ~15-20% faster.
Other CPU test show, that 7700k @ 4,8Ghz is in the middle of the list with 6 core stock clocks CPUs.
If you OC the 6 core CPU a bit, I think they will outperform the 7700k.
But that is legit with multi-core tasks.
If situation will demand single core power - 7700k will be the winner for sure.
