For what is worth, I have run Abit, Asus and Gigabyte boards and will not go back to Gigabyte. I had the P35-DQ6 returned it 3 times, finally ended up with smeone elses junk board and never got it running. I switched to the Asus Max board and it ran first time out of the box. I hit 4.06 on my Q6600 and though I did not stress it, it ran. The Gigabyte has impressive specs, but service is very poor. I have not used Asus customer service, but you know what, I have not needed it.
