I would buy it right now if it supported core unlock. I need to enable the fourth core on my X3 to make it until September.
I've read the reviews for this board, and it is seriously awesome, easily worth the extra over the asrock, but I need my ucc.
Consider that it is the first AMD chipset mobo out now to officially support SLI. So even if the Dozer isn't out, it might be worth it for some of you.
