Now I'm experiencing lots of stutering in games and benchmarks. MY rig is FX-6300, 8 gb ram, PSU 650w. I read a lot and tried almost everything but my card is just underperforming badly. I have the newest drivers, tried OC of the processor and turned Vsync off, no change at all. What bothers me is that the card never heats above 55 degrees and it seems that it doesn't work at full speeds. My motherboard is PCI-E express 2.0 could it be that's it's holding back the GPU? Is there a way to change a setting in the BIOS to get the card to run at full speed? This board has only UEFI bios that hasn't got enough settings for PCI-E gen control like others have what else can I do?
Asus GTX 670 and Gygabite 970a D-3 rev. 3

The 2.0 Isn't going to bottleneck a 670 at all. This is a strange problem, so I could say it could be the PSU, which could not be able to give the needed power (which is quite unlikely). Aside from that, I would say it could be a driver conflict, because the Mainboard BIOS doesn't have that much of an effect towards the fps. The driver is sometimes buggy enough that the GPU will always stay at sleep or idle mode, so you could be advised to clean install the drivers in safe mode. There is many tutorial regarding that case.
Hi thanks for the reply, I did reinstall a different set of drivers after making sure nothing is left with DriverSweeper I also did a render test with GPU-Z to monitor the card performance to be sure that it's not going idle I get GPU core clock from 400-900mhz and Memory clock from 400-1500mhz. Is this normal? What bothers me the most is that the card stays too cool. I know for sure that in full load it should reach something like 70 degrees and it never even touches the 60 degree mark, even with the OC of the CPU it just stays cool.

You can try to burn in your card, it should put the card onto it's maximum range of clocks. A Popular Burning software would be the MSI Kombustor, which is the one I use. It comes with the MSI Afterburner. After you write down the clocks, compare the clocks when gaming. IF there is a marginal difference, it's a driver bug and if a clean install doesn't help, you should mod it your own. Personally, I have never tried that and it's quite complicated from what I heard. So the best option is to do a clean install of windows and if it still didn't work, You're out of luck. Send back the card and get a refund

Tried a new copy of Windows 8 and it's still the same. On 3dmark 2011 I'm getting this http://www.3dmark.com/3dm11/7756627 I can't really say it's super low but it shouldn't be like that. I'm starting to doubt my PSU which is making coil whine noises but it's brand new Fractal Design Integra R2 650W and should be quite enough for my system.
Finally after a month of cursing and headbanging the wall (and a trip to the repair shop where they said everything is fine) I found a bios flash of the card did the job. The previous owner of the card flashed the latest bios which was somewhat incompatible with my motherboard and the GPU and memory clock were all over the place. Now everything is fine, my 3dmark score jumped from 4800 to 7200 and the card works great I hope this helps someone with the same problem.
