Native quad core means a single piece of silicon containing 4 cores. Connectivity between the cores has nothing to do with if it is a native quad core cpu (Both companies will do it differently). So multiple chips in one package or multiple packages on a motherboard is not native. That means...

Should have more info than you could care...
The issue you described can occur just by adding an X-FI card. It does not affect any games just 3dmark. So it is not really a big deal unless you benchmark a bunch.
Your "fix" has me wondering. I will pass that information on to ATI.
I get early sample ATI cards (for testing) so I have had X1950 XTX CF for some time. There is no known issue with 6.9 and CF. They need to look for some other trouble. One issue I have found is 3Dmark05 and 06 benching strange on some boards with an XFI card installed. I have had this trouble on...
Space to me is going to be a major issue. Some people had mentioned E-ATX as a solution but it is not. E-ATX does not make the board "taller" for more slot room but "wider" so that the motherboard has room for things like a 2nd CPU or additional ram slots. (AKA a server board.) So a totally new...
I have tested the XFX 7950 GX2 on the A8N-SLI (not DX) and it worked fine. The board had the latest bios installed no issues. You should be good to go. ;)
Sometimes failures can take time to occur. I had a customers system with a pair of 7800 GTs in it. We had tested the hardware for 24 hrs...no problems. We watercooled the cards and built the system. It ran fine for a week while we installed the OS, Updated, OC'd and burned the system in. We had...
We are looking for a little help on our site so I will keep that in mind. I will help for nothing as I just want your system to run right. :)
On the systems I have built we have added no additonal drivers for the FX-60. (We are looking at the dual core optimizer.)
Your temps are real good...
Again I vote change the PSU and retest.
Just to give a little proof I have worked with CF and are not just guessing.
2nd company down is mine. ;)

Ohh and don't return everything and rebuy.... but if a full refund on the CPU, MB...
This is true. I have heard that there is going to be a Hotfix until the next Cat drive is released.
Don't regret it. Once you get your bugs ironed out it will rock.
I have a ton of experience with CF (and SLI for that matter.) The flickering and the red LEDs on the cards flickering more specifically leads me to believe there is a problem with the PSU. The red LEDs on the card only light up when the cards are not getting power from the AUX PCI-E connection...
