Hello,

Sorry for the poor title, I wasn't really sure how to word it.

GPU: EVGA GTX 1080 Superclocked
CPU: Intel Core i7-4790k
MotherBoard: Z97MX-Gaming 5
RAM: G.Skill 16GB Ripjaws (DDR3)
PSU: Cosair 600w (Not sure of the model just the brand and wattage)
HDD: 2x st1000dm003 (My main HDD is a little tuckered out, but this wasn't an issue for my 970)
Monitors: 2x BenQ GL2450 (24 inch 1920 x 1080)

Yesterday I received my new 1080, a EVGA GTX 1080 Superclocked to be exact, and I'm not too happy about the results. I upgraded from a GTX 970 Zotac and have been met with mixed results, some games like The Witcher 3 can be played on max settings at 1080p with a solid 60 FPS, the same with Dark Souls 3 and War Thunder. However, other games like GTA V can't hold a stable 60, even on lesser settings than my old 970 could handle no problem, I can go to certain areas of of the city and be met with a constant 40 - 45 FPS.

I'll shan't bore you with a whole list of games that do and don't work. The point I'm trying to make is that my 1080 isn't performing as well as it could, the worst part of it is it can handle a game like The Witcher 3 on max settings just fine but struggles to hold a stable 60 in a team fight on Dota 2 which makes my problem all the more confusing as to why it's happening.

All my drivers are fully up to date.

Some friends have asked if I could move the GPU to the top slot on my motherboard, I cannot, the RAM wouldn't allow it to go there, also the 970 sat in the same slot.

I'll be responding as to comments as soon as I see them, thank you for reading.

*UPDATE*

A friend threw the idea around that maybe my PSU wasn't powerful enough for my rig, is this a possibility?

*UPDATE TO THE UPDATE* I have my second monitor plugged into my motherboard via HDMI, so it uses my integrated graphics on my CPU. When I unplugged the monitor from my computer my performance increased! Where I would get 45 FPS on GTA I would get between 55 - 60 FPS. Similar to Dota 2. With just my main monitor plugged in my FPS barely strayed for 60.

Does this mean that it is a PSU issue? I have a theory that when the second monitor is unplugged the CPU doesn't need to draw more power away from the GPU to display an image on the second monitor with the integrated graphics. If I had a better PSU both components would get the power they need, is that plausible?


 
You needed to completely remove and reinstall the GPU driver when changing the board. So...

Download the latest driver from nVidia, download DDU (Display Driver Uninstaller), Uninstall the current driver, run DDU and restart as needed. Then install the latest.

You care probably being hindered by the old driver not updating properly.

Done as you've suggested, and although there were GTX 970 drivers still on the system doing a complete wipe/reinstall of the display drivers hasn't sorted my issue out. Regardless thank you for your input, getting those old 970 drivers uninstalled could only help my system.
