That may very well be the case. I only have a 24" Acer 1080p G-Sync monitor so I can't say until I have something with a higher res. Aye. Based off what this Asus engineer has posted for similar mobo/CPU then it's fairly low! https://hardforum.com/threads/official-asus-p8p67-series-overclocking-guide-and-information.1578110/ I haven't tried going higher, I was trying to play it safe. But I reckon I could hit 5GHz with a more substantial increase in voltage and cooling. My Corsair H100 won't cut it.
