My current motherboard is a P8P67 LE and I was under the impression that I was unable to overclock it through regular means with this motherboard. I am a pretty big noob when it comes to overclocking and have no idea where to start as I have never done it.

I only recently found out that my motherboard can overclock through the BIOS. (not my image)

You have efficient mode on the left normal in the middle and the OC on the right.

Upon selecting this built-in OC my CPU goes up to 4.3GHz which is fantastic for me because I have been playing Guild Wars 2 and it improves my FPS by about 10, with MMOs being CPU intensive.

After a short while of gaming my game gets choppy at times and what would normally be 55-60FPS with a GTX980ti drops down to 40-45 and down as low as 30.

The CPU sits in the high 60s low 70s and the maximum temperature recorded has been 79. Could this be causing the issue of sluggish gameplay once it's hit a certain temperature?
 
I would not use auto oc software at all as it always over volts cpu. I would recommend to do it manually. On this cpu I would consider max temp of 70 under synthetic benchmark max

I would advice to turn off auto oc. Also try to read guides on how to oc you cpu. There are many up there. Just dont exceed voltage of 1.4v on core (although it depends on cooler you have as increasing voltage, increases temps so if goes beyond 75 Celsius degree, the chip will start to degrade.).

Answer to you question is that after time you cpu heats up and when certain temperature is reached cpu will protects it self and throttle down so this is why game becomes laggy.
 
The CPU wont start throttling until 90C+.

I would really recommend manually overclocking. You can access it in advanced mode on asus boards.

If you need help there are plenty of guides but I can give you some help as I have a sabertooth z77.
 
I followed this guide: https://www.youtube.com/watch?v=WMZoWOpry40

I followed it up until I get to the 5 minute mark, after this point I don't have any of the options he has in the DIGI+ VRM menu so I can't control my voltage on the CPU.

I saved my settings at that point and have achieved a 4.5GHz overclock at 1.371V, idle around 40degree after booting up. Not sure if I have done it right but I will see how it goes after a few tests.
