Well, my bad luck continues
After getting poor scores in metro benchie and getting lots of help from a lot of ocn members, I took off the blocks and tested the cards. Found one card that is not working. So basically, I had been running dual crossfire all this time. The culprit would crash if plugged in by itself and/or crossfired w/ another card. RMA time, just shipped yesterday.
Also, my mb is quirky, I have the "sleep mode" issues that is common in a lot of p67 boards. I've tried a lot of things (especially from the [H]ard forums) and nothing. This only happens when I oc my cpu. I'm getting different feedback from a lot of helpful members; some say to rma it, others its an Intel chipset issue and a bios update in the future should correct this. I'm going to contact newegg and see what they can do since I already paid shipping for the bad 6950 before my mb return window is gone.
Still, I'm playing metro in 3240x1920 is great and in medium settings my two stock cards are keeping up. Something that took three gtx470 to do is being done by two 6950 and running a stock 2500k (because of the sleep issue).
I should change my alias to "We-R-Bad-Luck"
