Good looking mainboard, but it's hard to get worked up about a 990FX chipset board when AMD's new stuff is just around the corner. Maybe it's a little late to the party?
I was using an FX-9590 CPU and Gigabyte 990FX Gaming G1 board recently. It was an extremely solid choice as I'm sure that this ASUS board is. It was very stable.
I gave the system to my son to use, and he loves it.
