New GTX 970 underperforming. Old CPU, Bottleneck, or improper install?

I recently purchased a EVGA GTX 970 ACX 2.0 and so far it has definitely been a worthwhile upgrade over my old SLI 580s.However, I am not sure it is performing as it should be. I used Rome 2 and Shadow of Mordor as my benchmarks as the other games I own are either not tested by the websites or does not include a built in benchmark.

I own an Alienware Aurora Area 51 system purchased in 2010 with the following specs...

CPU: i7 980x 3.33ghz
GPU: EVGA GTX 970 ACX 2.0
RAM: 12gig @ 1333(I think)
HDD: Two 1TB HDs @ 7200rpm
OS: Windows 7 Ultimate
MOBO: Unknown, Alienware doesn't know and I can not find any information on my system physically or virtually, also having tried 3rd party services to identify it to no avail.

I found a benchmark for Rome 2 here: http://www.anandtech.com/show/8568/the-geforce-gtx-970-review-feat-evga/10

In their review of their 970 they got 80fps at stock clock and 85fps with the factory overclock at 1920/1080. I used their same setting and only achieved 65fps average. The main difference between our systems is their CPU is clocked at 4.2ghz and is much newer, me having an i7 980x at 3.33ghz. They stated they lowered shadows to medium as it is a huge CPU draw in that game so I am not so sure If I am just CPU bottle necked or not. If it is CPU would unparking my cores possibly fix the issue? My system seems to run with about half of its cores parked but I know most games do not utilize that many cores to begin with so I do not know if it matters in the slightest.

I used this as a reference for Mordor: http://wccftech.com/shadow-of-mordor-benchmark-gtx-970-73fps-maximum/

I used the same settings as they did in the video (although I noticed his motion blur only said Object and Camera where mine says FXAA + Object and Camera) and achieved 68 FPS with highs in the mid 90s and lows in the 40s compared to their 73 with highs in high 300s and lows in the 40s. Not a huge difference and may be back to my older CPU and possibly a different version of the game as mine has FXAA added I believe but am not certain.

These are the only 2 games I have that are taxing enough and include a benchmark, BF4, Watch_Dogs, and Far Cry 4 appear not to have any benchmark but run well enough maxed at least to my eyes.

Another thing I should probably mention is that I am not entirely sure I installed the card correctly. I had the GTX 580s before and figured the same driver warranted nothing special to be done for the new card. When i saw that it displayed as if there was no driver I simply reinstalled the current Nvidia driver and checked "clean installation". I do not know if what I did was in error or is acceptable for Nvidia cards. Also I have "Texture Quality" in the Nvidia Control Panel set to "Very High" if that makes any tangible difference in performance.

Lastly, I believe but am not certain I am seeing more texture clipping and pop up when I run the Rome 2 benchmark, as well as a quick desync in the marching formation at the beginning of the benchmark which I do know for certain was not present when I last bench marked the game a year ago or so. that could be due to it being a different version than what I tested before but I do not know. The clipping and pop up just might be me being more critical than I was previously so I can not confirm if it is actually an issue or not.

Any and all advice is greatly appreciated and I apologize if I rambled, simply didn't want to leave anything to the imagination and cover everything I could think of. I hope something like an overclock could alleviate my errors but if it is something else like an improper install or who knows what I would greatly like to know and would value your input.

Thank you!

I would wipe the drivers and install them again. Rome 2 can be cpu intensive and overclocking would help a bit. As for the motherboard it will have pcie 2.0 which is more than enough bandwidth for any current gpu so no worries there. Plenty of people (myself included) you the old overclocked i7's for gaming and they are really much of a bottleneck for that purpose. Since you have what was once a $1k cpu I would overclock it a bit and use it as long as I could.

I am fairly certain I have PCI 2.0. I've looked into that before and from what I've found the performance difference between PCI 3.0 and 2.0 is almost non-existent, something like a .5% difference at best. I do not remember the exact amount but it was miniscule.



I have been heavily considering overclocking my CPU as it is liquid cooled but from what a more tech savvy friend says the liquid cooler on it is a mediocre one and I also have absolutely zero experience overclocking so I am concerned with damaging the aging CPU. What is a safe temperature threshold for a CPU in your opinion? Mine sits idle at 30c-39c. I will also try wiping and reinstalling the drivers later with driver sweeper.

Thank you both for the quick replies!
 
I really doubt that overclocking your cpu will help out that much. Check your cpu usage while running those benchmarks and see if your cpu is running at full clock speed and has 100% usage on the cores. If it is running at 90% usage on stock clock speeds, than overclocking your cpu won't help at all.

I unparked my cores and monitored my temperatures while I ran the Rome 2 benchmark just to get a reading and my CPU never went over 35% usage according to the Windows Task Manager, used only 5gb of Ram, and my temps were CPU 45c-52c and GPU 75c by the end of the benchmark.

I believe some or all i7 980Xs came with a "Turbo Mode" that increased the clock to 3.66ghz when needed. I do not believe mine has this feature and if it does I believe it is off. Toms did an article over overclocking with it that someone might like to look at: http://www.tomshardware.com/reviews/core-i7-980x-efficiency,2590-2.html
 


You can turn the turbo feature on in your bios.

I will have to recheck but I did not see an option for it last time I was in my BIOS.

I just ran MGSV: Ground Zeroes, Hitman: Absolution (which happens to have a nifty benchmark), and Rome 2 and got CPU usage of 35%-45%, 45%-55%, and 30%-35% respectfully. Is CPU usage this low a bad sign or possibly from something I've done? It is kind of worrisome that I am not getting higher usage I think.

I DID find the option for Turbo Mode in my bios and it was enabled however I have never, ever, seen my ghz rise over 3.33ghz. It said in "specific applications" the ghz is boosted. Under that option I found 2 preset overclocks and enabled the level 2 version however upon restart I have noticed no increase in my ghz in or out of gaming and no performance difference in my benchmarks. I am using my ParkControl software to monitor my CPU's ghz. It lists my Ghz as 1.57/3.34ghz and when under load 3.33ghz/3.34.
