i7-5820k Questions

Alright so I recently looked into overclocking and managed to OC my i7-5820k to 4.6 Ghz @ 1.31 vcore.
Questions:
1. Intel XTU Bsod at 1.31v when I bench it but during real world usage (gaming etc) everything works fine. Is it ok to leave it at 1.31v or do I need to stress test my cpu until i find a voltage that doesnt bsod under such stress test?

2. Is it true 1.4v is the maximum for safe 24/7 oc voltage if temps are below 85C sustained while mitigating cpu degradation? Would i be safe to try perhaps 4.7ghz at 1.4v?

3. What exactly is processor cache ratio and is it worth OC it along with my 2400 mhz ddr4 ram? Does OC benefit both real world performance in any way?

4. Is my chip OC to 4.6 ghz similar in performance to the newly released i7-8700k? Is it worth upgrading my setup now?

Thanks in advance.
 
I left the cpu input voltage to auto and it fluctuates around 1.904-1.92v. What would be the upper limit? 1.95v?

As for overclocking the ram, doesn't it affect the bclk along with the overclock on the cpu? My ram is currently at 2400 mhz. Timing (15-15-15-35-1.2v)
 
So after a series of testing i was able to get the following.
4.7 @ 1.36v at 62 C
4.6 @ 1.275v at 55 C

Keep in mind that these are "real world" testing by doing the usual things day to day and is rock stable. If i stress test it, 4.6 requires 1.31v and 4.7 instantly bsods at 1.4v when i stress test it. Also to note, it only goes up to those numbers when i game which is around 3-4 hours at most per day. The rest of the day it idles around 25 C ~ 1.2 ghz @ 0.76v. Which one should i run 24.7?

I used intel XTU.

As for an upgrade, im guessing the most cost effective choice would be to wait until the prices of 5960x/6900k/6950x to drop and pick one up to extend the life of my current setup.
 
Is there much of a difference between the 5820k and 5960x? (Aside from an extra 2C/4T) Wouldn't broadwell-e(6900k/6950x) be a better upgrade with the node shrink/IPC improvement?
