Thanks for this man, i have the same board and the processor is on its way, was already thinking if i had to buy another board. As of today in the cpu compatibility they haven't updated that that the 3900x is compatible. I do modest gaming and modest video editing, I don't think I'll stress all 12 cores more than 10 mins on heavy load. Question, is it more recommended to allow the coreboost option enabled instead of a modest 4.0 OC fixed? Also, wondering which was the previous processor you had, was it the 2700x, do you see day and night difference others mention in the forums? thanks.
