.................While I was troubleshooting an issue with a certain game I managed to pinpoint an issue that I was able to study further. Enabling GEN3 with nvidia a lot of times may fail immediately but sometimes it seems like it's working properly (it did so for me) when it's actually not.
It causes driver timeouts with the all the X79 CPU samples I tested it on when the cards are adequately loaded. The windows driver has the ability to recover from these timeouts (most of the time..if the timeout reaches a certain threshold a stop error/BSOD will happen) but even when it does, it causes frame stuttering as the driver stalls for an amount of time.
The more video cards you have in SLI the more severe the issue is/becomes. Because of these findings I suggested that everyone keep using their cards on GEN2 (even if it seems like it's working fine in GEN3) as GEN3 provides nothing in terms of real performance with existing cards and due to this issue it can actually hurt it on certain load scenarios.
This is why nvidia is disabling GEN3 globally in the driver, for this platform, in the first place. If you get an IB-E CPU that is actually certified for GEN3 (instead of SB-E which is just "capable") then you should be fine for GEN3.
Note: AMD cards are indeed unaffected (or at least they're unaffected on these particular loads).

No, no damage....you'll see in Noden's post that it might not give you better performance but there is no harm to be done trying it out.
