4790k OC advice needed?

It's hard to estimate oc headroom as every cpu is different and it will do different clocks at different voltages. The best way to check it is to overclock it. Also when overclocking I would run something more demanding to check temperature.
You don't have to run synthetic benchmark such as prime 95 but cpu will be more stressed while running for example while running video rendering program for a 1 hour will be more demanding than runing a gaming. By doing this you can get a idea of what would be you maximum temps in worse case scenario.
For example my I7 4770k @4.5 ghz under prime 95 reaches temps in mid 80's however while gaming temps after a 1 hour of gaming are in mid to high 50's.
Lastly when overclocking remember to do not exceed 80 Celsius degree while in heavy cpu base application or stress test. Many people advise to use synthetic benchmark to test stability but this doesnt mean overclock will be 100% stable as there are many cases when prime was running for 12 hours and people have bsod after few minutes of gaming. Iwould keep temps under 60's celcius degree when gaming just for safety reason and possible future degradation of cpu that overclocking is associate it with. Hope this helped.

When I overclocked my cpu i7 4770k I set voltage at 1.25 and I worked my way up from 4.0 to 4.5 which was my max over clock as I needed 1.295 for 4.7ghz so I went down to 4.5 as my temps at 4.7ghz were in low to mid 90s. Just remember to do not exceed 1.3v for 24/7 on air but at the same time try to keep your temps velow 80 Celsius degree at max Because high temps will reduce lifespan of cpu dramatically.

1.35v is fine on DC chips for 24/7 use, due to improved power delivery compared to older hw chips. Real bench is a good test and more realistic than p95 etc. Temp wise as long as its not throttling when testing it will be fine. You won't see temps this high in normal use. My chip in sig maxes at 81c under real bench. 1.300v @4.7ghz, gaming it can be anything from 64-74c on the hottest core. Still well within safe limits. Theese are just hot running chips by design.
