First off thanks for any help! I am running a 560 TI SLI setup with a 850W power supply and a AMD FX-4170 OC CPU. I have been getting 3DMark scores that are lower than I am seeing other people reporting. This is also occurring in Unigine Valley benchmarking program as well. This has been a problem since I have tried to get the cards working together. They are both 560 TI's but one is a Zoltac and the other is stock. I have verified using the SLI is working using the Nvidia SLI indicator. Things I have tried: Updating GPU / CPU drivers. Toggling "No Snoop" attribute in PCI-E settings within BIOS. Updated motherboard BIOS. Turning off power saving mode for GPU. Installed Win 7 hot fix for AMD BullDozer CPUs (this gave a slight improvement). OCed stock 560 TI to match clock settings of the Zoltac card.

Do you think that is why I am getting the bad results and my GPUs are actually performing as they should be? Are there any programs that will fully verify they are working to their full capacity?
thats a very weak cpu for sli, you would be better with a stronger single gpu. is that cpu at stock speed? newegg had a deal on 8320 for 129.99 but they are sold out now. are you in the us? if your m/b supports vishersa
The standard CPU speed is 4.2Ghz so not a big difference. I'm not in a position to invest in a better CPU right now. Is there anything I could do to boost the performance with the SLI?
Yeah, by stop looking at benchmarks.. With that CPU you're never gonna be a benchmark king, so don't bother.
OP, your CPU is heavily holding you back. 2 x 560Ti's in SLi are a bit / somewhat faster than a single stock 680 which wouldn't do well with this quad module AMD process (equivalent to dual core Intel CPUs, perhaps at most the i3, when overclocked). You'll need to push the chip as far as you can, and even then, you will still get bottlenecked. A good option is stepping up to a FX83xx processor (or newer) if your motherboard supports it, when you are able to.
I OCed my CPU to 4.6Ghz like in the other scores which I have presented. I still don't see a similar score even though all the specs look the same. If the other people are running they same hardware how are they getting scores that are so much better.
CPU at 4.6Ghz was causing BSOD. I had to take it back down to 4.5GHz. Here are my results: imgur.com/a/TIQKp Sample results I'm trying to achieve: 3dmark.com/fs/11395
Try setting your physx option to cpu and see what happens. What I see is your physx numbers good but gaming failing. Somehow SLI might not be active or trying flipping the bridge around, I heard some people doing that fixes some issues.
I flipped the bridge and set Physx to the CPU. There was not much of a change. Results: imgur.com/0AJrOdM
