Hi Guys,

Recently I've got a new GPU (GTX 670) and tried to compare the results with ones from existing reviews (like for example http://www.bit-tech.net/hardware/graphics/2012/11/12/gigabyte-geforce-gtx-670-2gb-review/4)

While in this review the minimum fps is 62, mine goes as down as 35 according to fraps.

The video card is brand new, and the same model as the one in the review. Would this mean that my processor is just not good enough to handle it ?

I'm using an AMD Phenom 2 x6 1090t OC@ 3,7ghz

Thanks in advance for your help!

are you also benching on the demo as its shown in the review or are you talking about minimum FPS during regular game play?

What are the other specs of your system? most importantly the psu? you need to have a powerful enough psu to power your card and it should not start to undervolt it during intensive gameplay.

Is V-sync turned on coz it may affect the frames. Have you also monitored temps during gaming to see how hot your cpu and gpu are running. Use a software like coretemp to check that out.

Bottom line is 1090T is a good cpu and should be able to drive the 670 to it's potential. If you are seeing 100% cpu utilization but your GPU is underutilized, only then can you suspect your cpu to be your system's bottleneck.

It might help if you dive more deeply into their test setup to explain why your results don't match the results that they posted in that review. First point being they were using an Intel Core i5 2500k overclocked to 4.2 GHz. While the 2500k may not be the best performing Core i5 in Intel's line up, when its overclocked to 4.2 GHz it will easily out perform your Phenom 2 x6 1090t. Secondly they said that they benchmarked using "custom in-game time demos and manually played areas". If you don't use those exact same recorded time demos and play the exact same areas then your mileage will vary as well. You could be playing a section of the game that is more loaded down with polys and particles than the recorded demos that they were using. Thirdly your video card driver version could also be an issue. Both AMD and Nvidia are constantly updating their drivers to work better with certain games...some older, some newer. They are using GeForce 306.23 drivers, you might want to take a look at that as well. Finally the resolution can have an impact on your frame rate. The lower the resolution your playing at can use more CPU and less GPU than a higher resolution, thus resulting in lower FPS. Just a few things to keep in mind :)

Hi Satyam,

Thanks for your reply!

My other specs are:

4gb ddr 3 Kingston 1600 (OC)
Samsung F3 spinpoint 1 TB (doubt my hdd affects FPS, except just ocasional loading spikes)
Rasurbo gamin x power 650W
1920x1080 resolution

I use Vsync on, but it's pretty much the same without it in the "low fps" areas.

Temperatures are OK, neither CPU or GPU goes over 60 degrees (thermaltake custom cooler, windforce 3x)

I ran the same test, and the lowest was about 45 fps. I guess most of the rest met with the review.
The 35 fps I met was during actual gameplay, you are right.

Still, how can I evaluate my system's performance if the reviews are let's say... more subjective? I read a lot of reviews and was hoping that with my new GPU I could play most of the games maxed with >50 FPS. Watching it go down in the 30s makes me wonder what am I doing wrong ? Is my CPU holding me back ? Do i need to OC my GPU ?

And that's why i'm here, bothering you all :)

Hi Rolli,

Thanks for your reply!

I have an 650W Rasurbo power supply, I guess that should suffice ? Still, in case it may have some issues with the voltage, could it cause low fps ingame?

I mean, from my understanding it was like "either your graphic card powers up, either it doesn't work at all".

Also from your link, I guess the Intel procs do have some frames advance over AMD.

Hi Todd,

Thanks for your reply!

You are totally right. But I read a LOT of reviews and all of them had similar results. So I assumed I could take it as a whole...
But in this case... how could I really evaluate my system's performance? I mean, to make sure my system is performing as it should be.

What actually concerns me is that, I ran an Unigine Heaven benchmark 3.0 test. Now this is said to be very non CPU intensive anyway.
With the settings from a benchmark, they got 1800+ score. I get around 1400 with the same settings, same graphics card. I'm pretty much confused so I'm trying to take every element in consideration.

I'm running the latest drivers, 314.22

PSU issues would be crashes and shut downs, it would not affect performance. 650watt is sufficient although I am not familiar with your PSU.
In my second post you will see the X4 980 @ over 4GHz (X4 at higher clock should be faster at gaming than your X6 at lower clock) not coming close to the 2600K which would be very similar to the 2500K used in the test you linked to. Crysis 2 is one of those games that is CPU dependent.

Although what Rolli's saying is almost certainly the cause (meaning it is the cpu IPC power that is making it lag) what makes me wonder is the huge margin by which OP's cpu is staying behind. Even in crysis2 link, the % difference is what like 10% maybe a bit more between 2600 and the 1100T but in this case, 1090T is less than 50% of 2500K??

I feel this can be improved.

Agreed as settings and in game play have to be identical to get comparable results
