Low frame rates/stuttering with new card (4gb 770)

I recently upgraded my graphics card from a 560 ti to a Gigabyte 4GB Windforce 770 GTX, since the upgrade games have actually been running far worse with low framerates and stuttering even on medium settings.

I have tried the regular drivers and used driver sweeper to completely wipe any old drivers that might have been causing the issue and im running the latest BETA drivers for the card. I am really out of ideas, i think its possible my motherboard might not like the card as it is quite old now and iv never upgraded it.

I have used Afterburner to show me GPU usage in games and while im not certain on whether it even should use a lot, i would be lucky to hit 40% running Rome 2 for example. certainly FRAPS gives me the FPS at around 20 for most of the game and whenever any sort of fight occurs it drops to 8 or 9.

If you haven't figured it out im not exactly a computer genius :( 

I originally bought a Dell Studio XPS 8100 back in 2009/10 and so im not entirely sure what motherboard it is running which is why i suspect this might be the problem.
Specs:
Windows 7
Gigabyte 4GB GTX 770 Windforce
Dell G3HR7 motherboard (not sure on this)
Intel i5 CPU 650 3.20GHz
Coolermaster 650w psu
12GB RAM
some sort of 1TB hard drive (whatever came with the pc)

If anyone can offer any insight as to why the card isnt performing to levels i would expect i would greatly appreciate it!

ps. I have tested the card in a friends system and it works like a charm in his rig.

Hi roadrunner,
The reason for the low frame rates may be due to the old motherboard that may not be able to run it effectively (maybe doesn't support PCI 3.0 or just has PCI 1.0). It may also be because the memory bus on the 770 cannot handle the 4GB properly.

Thanks for the reply :) 

If it is a motherboard problem would their be any relatively cheap but reliable motherboards you recommend? And i don't know much about the inner workings of graphics cards but if it cannot handle the 4GB would this actually cause such poor performance? even my old card which was just 1GB seems to outperform it at the moment.

I should add that while the card fits in the case, space is of a premium, i dont know if this could be related

Hi again roadrunner,
I am very good with that aspect of graphic cards, so i suggest you contact Nvidia regarding that issue.
Also, i cannot recommend a new motherboard without knowing your CPU. Please include that in your reply.

Thanks

my CPU is an Intel i5 650 3.2 GHz, at least thats what msinfo32 tells me, is this helpful? i have never upgraded my processor so i know it is also, like my motherboard, quite old now.

thanks for helping!

Which CPU does your friends system have?
I think the problem is your system has run into a CPU bottleneck, the i5 650 is a dual core processor, although it does have Hyperthreading I don't think it's going to help with games.
It is also possible the motherboard cannot fully support the new card, you'll need to find out the make and model of the 'board and go to the manufacturers website to see if an update is available-most 'boards have this info printed onto them BTW.

Though i dont know the specifics, he has some sort of i7 that i know is better than mine, if the cpu is causing the issue, how come i don't get the same performance drops using my old card?

Im just looking at updates on the dell website now, i don't really know what im looking for; it lists updates like BIOS, Chipsets, Video, Audio, Application etc.

Thanks for the help :)

Maybe your old CPU could handle the old card, but maybe the new card requires a quad-core processor for some bizzare reason, or your CPU has problems related to the 4GB of GDDR5 memory. As coozie said, try to find updates for the graphics card, the CPU and the motherboard.

You're looking for BIOS updates.
A word of WARNING which I should have issued earlier: If you are in any way unsure about how to update the BIOS, leave it alone and seek local advice, maybe even drop it off to a local computer store to have it done. Make a mistake and the motherboard will be rendered useless and although it is possible to recover it may take some time and be expensive.

I successfully updated the BIOS and i haven't noticed much change, so is it likely to be the processor limiting performance?

It may be the processor that could be limiting the functionality of the Graphics Card, as you said.
So, your best option now, would be to buy a new processor, which of course means new mobo, perhaps new PSU, perhaps new RAM.

PHEW! I was a little worried there!
If you're still using Beta drivers, try using the current, latest WHQL certified ones for your card and see if that helps.
Also download and use GPUZ, start it and there is a small panel showing the PCI-E information, to the right of that is a little blue question mark, click on that to start the render test and see how the card runs (my 7950 shows PCI-E 16x @1.1 on idle but ramps up to the correct PCI-E 16x@ 2.0 during the test).

I don't really have the budget to but lots of new parts unfortunately, not much left over from splashing on the card.

Before i run the render test it reads PCI-E 2.0x16 @x16 1.1 and during the test it goes to PCI-E 2.0x16 @x16 2.0, i dont really know what this means though.
