Running the test on a single stick in slot one right now. I'm assuming this has to do with the actual RAM and not the motherboard, yes?

It could be a bad stick of RAM, hence testing one at a time in slot 1.
 
If the RAM passes just fine one stick at a time in slot 1, and then fails to pass with all the RAM installed - then it is a bad motherboard.

You know, if you had read the zillion topics that are already out about 1080 bad perfomance, you wouldn't of even had to post in the first place.. A plethora of people have said to use DDU and reinstall drivers clean.. It's all over the place..

You know, if you had read the zillion topics that are already out about 1080 bad perfomance, you wouldn't of even had to post in the first place.. A plethora of people have said to use DDU and reinstall drivers clean.. It's all over the place..

DDU does not clean the registry very will and so DDU is only a part of the cleanup to remove old drivers and so on.
I stopped using DDU after is caused issue with my Chipset Drivers.
 
On a Side Note that I have learned to do is delete the two Keys listed below.
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Video
HKEY_LOCAL_MACHINE\SYSTEM\ControlSet002\Control\Video
It will error and say it cannot delete the Key, but that is ok as it cannot delete the Key itself nor the Default VGA Driver GUIDs.
What it will delete is all the GUID's for NVIDIA's Drivers. REBOOT After you delete the Keys.
This is the last item that I do before I install a New Video Drivers.

First stick tested. No errors.

Time to test the other stick. That is the vram. Being low isn't the problem. PhysX test uses the cpu so gpu will idle down while the cpu is doing the physx test.

You need to setup a nice fan curve since your card reads 86c in that screenshot

Before you do any rma's is your wifes setup running the same driver version? You can also try doing a fresh windows install

Hi minty fruits
 
Lets try a few things before you re-install windows. We know it runs benchmarks without freezing up so I don't think it's the motherboard. It's not your ram. I think it's your chipset. This would cause it to freeze up on some games by not getting the right pcie 3.0 x 16 bandwidth speed. When it doesn't have enough it freezes your card up. I bet your pcie speed is like pcie 3.0 x2 or x4. Maybe even lower who knows. We just know the fps isn't right at all. When you run at pcie x8 or below your fps will go down.
 
Download this The Intel® Driver Update Utility.  
http://www.intel.com/content/www/us/en/support/detect.html?iid=dc_iduu
 
Run The Intel® Driver Update Utility see if it finds a new update on your chipset. if it doesn't find a new update for your chipset re-install your old one over here https://www.asus.com/us/Motherboards/MAXIMUS-VIII-HERO/HelpDesk_Download/
I'm starting to wonder if your chipset isn't installed correctly. This would cause slow downs with the pcie slots not getting the right bandwidth speed they suppose to.

Let's try this second if that doesn't work.
Go in your BIOS 
go to advanced -> onboard devices-> look for PCIEX4_3 Slot Bandwidth. change the auto to x4 mode.
go to advanced -> System Agent (SA) Configuration->Graphics Configuration->PEG Port Configuration look for Auto change it to [Gen3]  save  changes and exit. Boot windows up see if your games have more fps now. If this doesn't double your fps or improve your fps in games time to re-install windows.
 
I looked at your motherboard manual and slot 2 is the only one that has PCIe 3.0 x16
 
1 PCIe 3.0 x1_1 slot
2 PCIe 3.0 x16/x8_1 slot
3 PCIe 3.0 x1_2 slot
4 PCIe 3.0 x8_2 slot
5 PCIe 3.0 x1_3 slot
6 PCIe 3.0 x4_3 slot
 
So make sure it's installed in the second slot.

Try this before you re-install windows
Go in BIOS again
go to advanced -> onboard devices-> look for PCIEX4_3 Slot Bandwidth. change the x4 mode to auto again.
Save changes and exit.
 
 

Alright change that back to auto then. Sorry about that.
 
Try this before you re-install windows
Go in BIOS again
go to advanced -> System Agent (SA) Configuration->Graphics Configuration-> look for Primary Display change the auto to PCIE
Save changes and exit.
 

So none of your games are higher. How about benchmarks?

I see. Ok one last thing before you re-install windows.
 
Go in your bios again and
go to advanced -> System Agent (SA) Configuration->Graphics Configuration->PEG Port Configuration look for
PCIEX8_2 change the auto to Gen3 and PCIEX16/X8_1 from Gen3 to auto save changes  and exit see if that does anything.
 
After all these changes if it still doesn't work. Don't change the settings in the bios yet. Just re-install windows again. Hopefully windows will see your new bios settings when it re-installs and windows will configure itself to your new bios settings and  everything will work then.

Mint, what type of hdd are you running and your wife's PC? The reason I'm asking is because having a great SSD in you PC helps to boost your FPS. Look at the reviews and see if they have SSD running in their test rigs that could be the turning point. I would also try the clean installation of Windows like a few suggested, but my suggestion will be, instead of doing the clean install my as well get a brand new SSD.
Also, I wanted to know how you have your hdd set up in the bios: IDE or ACH?
