According to that article all you have to do is a small registry edit to get your GTX 680 working at PCI-E 3.0 once again with current drivers. This is a huge deal for those of us with multiple GTX 680's. Being stuck at 8x PCI-E 2.0 is a no go.

You can test your PCI-E speed when the card is active (no idle it will go into power save mode) with GPU-Z:

Click on the little question mark next to the PCI-E speed line on the right to read the proper speed during rendering.

Wasn't there a comparison of PCI-E 3.0 vs 2.0 and it was less than 1% difference? And a test between x8 and x16 and it was less than 3-4%?

Most of those tests are ancient nor did they take into account 3-4 GPU's in multi-display setups.

If you are losing 3-4% running a single old GPU on a single monitor I couldn't imagine how bad 3-4 overclocked GTX 680's would be hampered running multi-displays at 8x PCI-E 2.0

If you read the thread you will see that people have already got it working.

Someone reported his second card not getting the fix, but i assume that was because the registry fix was per-device and he didn't perform the same fix to the second card.
