I've had two DFIs, the 965-s dark and the one in my sig.

The latest one is great, no problems at all. My only gripe would be that the sata ports and the memory slots are cheap and flimsy for a high end enthusiast board that needs to be physically accessed a lot. I was surprised by that when I first built it up. Otherwise completely great board and bios - 5 stars.

The 965-s dark was really poor quality. The whining coils were just too much. I boxed it up and shipped it back the same day.

Never called support because the only issues I had were obvious. Never posted at DFI Club, but I read articles linked in the thread for my board which were helpful. I must say that the guys who buy DFI off the shelf and post results here (dfi faithful) are the best feature of these motherboards. Comparing notes with other unbiased users is the bomb. Some of the sponsored guys seem a little defensive at times but very helpful too. : )
