For anyone above saying I posted bad advice about keeping and using the board until I have problems I'll do just that. I bought a $100 board, enjoying it now and will enjoy it for a long time to come. If you have important data that you don't want to lose, its your job to back it up using multiple methods. Always expect your drives to die, then if they do, you're already covered.
Like utnorris said, he's enjoying his SB setup, I'm enjoying mine. If you want to send it back, go for it, but you'll go without it for at least a few months, all while I'll be enjoying mine then probably replacing it when X68 comes out. I have the luxury of having multiple setups and a lot of flexibility, so if it dies I won't be broken hearted.
I'm actually really curious to see if this board will fail or if I'll suffer the symptoms of a failing SATA controller. Only time will tell and until then I'll call this board a Special Edition.
Enjoy your Sandy Bridge man. I've enjoyed mine for the last couple weeks, but honestly it was really not much faster than my Q6600. Even at 4.5 Ghz, the SB did not impress me. The biggest upgrade for me was my SSD and my 580 GTX. I used those in my Q6600 for about 3 weeks before buying my SB parts. Those two parts alone improved everything for me more so than an entire new SB build.
The only thing I won't be able to do with my Q6600 box is go SLI and NV Surround since the board I have doesn't support it. I'm sure I'll live though. Fortunately I had not yet purchased my 2nd 580
Luckily this chipset design flaw comes around and gives me the exact push I needed to return all the stuff I bought for Sandy. Guess I'll build a new PC in 2012.
