Low Performance XFX 7950

Hello there! I am having an issue with my XFX 7950 DD. It feels like I am not getting the optimal performance for my PC. I have the 13.10 AMD driver installed and my 7950 is overclocked with MSI Afterburner.

My Passmark Performance score was 1546.7 if I remember correctly, isn't that low?

System specs:

AMD Athlon II x4 640 (Soon to be upgraded to FX-6300)
8GB Kingston HyperX Blu
Gigabyte GA-970A-DS3
FSP Bluestorm II 500W <- Could this be a problem?
Antec GX-700 Case
XFX 7950 DD Overclocked

Could my crappy PSU be an issue? I will upgrade it if so.

Any Ideas Welcome!

I want my system to be running optimally because I will be getting new games like Battlefield 4 and Need for Speed Rivals.

Any Ideas People??

Thanks.

you are correct..cpu bottleneck...your cpu is holding back your gpu power

Forget passmark.

What games are you getting low FPS on?

Oh and that board is NOT meant to run FX CPUs, it can, but its not suggested.

you are held back because of your CPU. Athlons are budget gaming CPUs mainly because they lack level 3 cache and they have low operating frequency. You will notice decent boost when you upgrade to FX 6300. I sugest that you would get an aftermarket cooler for the FX and get the most out of that chip via OC (arround 4,3 - 4,5 GHz)

I am getting low FPS on Just Cause 2 ETC.

The only reason I am worried about the 7950 is because it doesn't feel like much of an upgrade from my 7770.

Oh, The board will run a FX CPU. it's in the supported CPU list. Why isn't it meant to? Other people have.

I already have an Arctic Freezer Pro 7 Rev. 2, that should be enough?

Would my 500w be a issue?

How does a CPU hold back a GPU's performance? :)

Easy, the game requires more CPU power and then the GPU does not get fed resources from the CPU fast enough.

HOWEVER it could be another problem like overheating, did you check your temps?

And yes it could be PSU related too since that is a REALLY bad unit. But only way to check that is with another unit.

My Athlon goes no higher than 50-55 degrees at max load.
The 7950 got up to 80 degrees when testing with FurMark, is this normal?

Thanks :)

Jip, temps are normal.
When you play games, where does your GPU peak? 95% + ?

When playing Just Cause 2 Maxed Out, the GPU usage is about 94% and at around 120FPS (MSI Afterburner)

This is at 1080p by the way :)

Then why are you complaining? Its not necessarily a bottleneck of the GPU but just that the game requires more CPU power in general, OR its a power supply issue IF there even is an issue.

I would replace that PSU just because its a crap unit.

I was just expecting a big boost from a 7770, but the difference isn't that huge.

Thanks for your help!

Thanks :) 

P.S - I will replace the PSU to a Corsair CX600.

Well at that FPS, it will not scale any further.

But in games like BF4 and that sort of newer game there will be one hell of an improvement.

You are using an old game at insane FPS already. So not really the best comparison.

Get an XFX550w or similar PSU, the CXs are nice, but not that nice.

I should be getting Battlefield 4 & Need for Speed Rivals on Friday/Saturday. I will post back results then.
