fabyo, happy to help, it is fun to OC, but time consuming. I hope others post their favorite benchmarks, tools, and tuning tips here too.
You need at least 2 apps to tune for better performance on the G750. One for CPU and one for Graphics. And, a monitoring tool for both - but in this case both tuning tools come with their own monitors.

This is what it looks like, 2 panes, one for setting, one for monitoring - the monitoring one has a slider to view more values/graphs. These are my current everyday settings. But, I OC per benchmark, some take 5500mhz memory, some 5150 - all run fine at stock voltage at highest GPU OC - 932mhz.
Intel XTU or Extreme Tuning Utility will allow increasing / decreasing various CPU / integrated GPU settings. For the G750 I bump all the multipliers for core/cache up to maximum, and then reduce the Voltage Offset down (negative) as much as possible to reduce power / heat under load. I start at -100mv. My G750JW was stable at 100% CPU at -100mv. My G750JX is mostly stable at -75mv, but I run it at -50mv to be sure it is stable.

Here is the profile I am using, you can unzip and Import the .xtu file into your XTU in the Profile section (see jpg):
There are lots of system monitor programs, I will post some more of those later. And, there are lots of benchmarks. You already are running 3dmark and 3dmark11, which are a good start, and shareable over a long period of time - which is why they are so popular.
Here is my 3dmark Fire score, after using Asus Tweak Tool and Intel XTU + some Nvidia control panel, 3d tuning.

What drivers were you referring to that you have that are different?
I am running Nvidia 327.23 WHQL release driver, and all the latest Asus drivers downloadable from support.asus.com.
The 3dmark results are from 326.80, but I am getting about the same numbers with the 327.23 release so I haven't rerun them all and posted them online.

hmm what would be the battery life savings by undervolting 50 mV on the JX?
Ah, we are all thinking in terms of battery now 🙂
No, it is a heat issue, reducing the heat generated for long running CPU intensive work. Reducing heat reduces the fan noise, and can result in a higher sustained CPU speed - like right now, I was running at 0mv (no negative offset) and was running at 3.19ghz, and now at -100mv it is running at 3.36ghz!
Temps:
0mV
-100mV
CPU Speeds:
0mV
-100mV
