I have the 2GB nVidia GeForce GTX660 card, installed in the top, PCI-E 3.0, slot on my ASUS P8Z77-V LK motherboard.

My CPU is the Intel i7 3770, with Ivy Bridge.

However, with the Unigine Valley Benchmark program, I only average about 30FPS, and I think it's because I'm getting bottlenecked. GPU-Z readout says that my Bus Interface is x16 @x8 3.0 (while the render test is running. While it's not running, it says the same thing, only 1.1 instead of 3.0).

I've changed the BIOS setting for this card to Gen 3 from Auto. All my drivers are up-to-date. I do have an addition 2GB onboard video memory.

What am I doing wrong? I don't understand why the card isn't running at x16.

nope. even if the card is running on a pci-e 3.0 slot at x8 instead of x16, it isn't being bottlenecked. pci-e 3.0 x8 = pci-e 2.0 x16, and there isn't a gpu made... ANYWHERE that can saturate that. even a titan, or a gtx 690, or a hd 7990... none of them will saturate a pci-e 2.0 x16 connection.

if those can't do it, then your 660 isn't saturating the pci-e 3.0 x8 connection.

Gpu-z and some NVidia info is incorrect. Anyway Run OCCT, in the gpu test set the FPS value @0 to disable the limiter and run. http://www.ocbase.com/ your true fps display top left.

Thank you for the explanation. I'm not sure where the issue is coming from, then. However, I did figure out my stated issue: the reason my card was reading at x8 was because my ethernet card was in the wrong PCI slot. Moving the ethernet card to the bottom PCI slot fixed that problem. Now I just need to figure out why my computer isn't performing as well as I'd expect.

i find sluggishness and under performing hardware usually have several common causes.

1) high temps
2) bad power/psu
3) bad ram
4) bad/slow hard drive
5) bad drivers
6) virus/malware/bloatware
7) windows needs a spanking/re-install
8) strange bios setting/bad overclock
